Back Strain: Symptoms, Causes and Treatment Strategies
Back Strain: Symptoms, Causes and Treatment Strategies
A strain of the back muscles mostly causes localized pain in the area of the muscle/tendon injury accompanied by stiffness, limited range of motion and difficulties maintaining straight posture. Timing is very important when it comes to muscle strain.
Most muscle strains usually happen while lifting something very heavy or doing a sudden movement. Many individuals experiencing back pain due to muscle strain may feel a popping sensation at the moment of the injury which usually prompts them to seek medical attention.
They may have difficulties straightening their back up after the onset of the pain and usually maintain a semi bent position to avoid severe pain. That is not to say that muscle strain cannot come gradually. Even in this case, however, the individual can usually remember the moment when he felt sudden uncomfortable pain in the back which became progressively worse with activities.
Frequently, however, the pain can also be felt around the base of the spine and in the buttock area. Occasionally, pain may radiate into the buttocks. Under normal circumstances, pain due to back strain does not radiate down to the legs.
Pain radiating down to the legs is usually associated with nerve compression, but it is also frequently seen as a result of trigger points in the gluteal (buttock) muscles. Back strain is not a serious condition and most individuals with acute back strain recover spontaneously within 1 to 2 weeks.
When muscle strain is caused by a sudden movement, it is generally a result of preexisting tightness in the back muscles which has developed over a period of time. Tight muscles are less flexible. Decreased flexibility results in limited ability to respond to sudden demands for muscle extension beyond the normal daily activity.
Therefore when the muscle is required to suddenly extend beyond its limits, such as when catching a falling object or catching ourselves from falling down, a strain can develop in the muscle or the tendon. To prevent further injury, the body triggers protective mechanism which manifests as muscle spasm.
The final outcome is stiffness and significantly limited range of motion with great amount of pain when trying to move in any direction.
Activities involving excessive forward bending of the spine constitute one of the most common misuses of the back leading to increased vulnerability to a variety of injuries. The forward bend position stretches the muscles and tendons of the back to a point where very little control can be exercised over the spine’s position.
Therefore lifting objects in forward bend positions can easily strain these muscles and their tendons. Additionally, forward bend position creates an uneven pressure on the spinal discs making them significantly more prone to injury.
Poor posture
Poor posture is one of the main underlying causes for the development of back strain. It generally refers to either too large or too small curvature in the area of the lower back. Over a period of time, poor posture leads to muscle imbalance and strain of the muscles/tendons in the back.
Spending extensive period of time in uneven position such as being twisted sideways or bent forward, also puts great stress on the spinal discs predisposing them to injury.
Poor physical fitness
poor physical fitness, excessive weight, sedentary lifestyle and lack of flexibility are also among the leading factors predisposing individuals to back strain. The result is poorly conditioned back muscles that lack sufficient strength and endurance to respond to increased physical demand when called upon.
This is why sudden unexpected movement, or performance of new repetitive task requiring the use of back muscles, easily result in back strain.

Patients with sciatica usually experience the familiar electric jolt like sensation propagating along the back of the thighs sometimes all the way to the feet. The sensation of pins and needles or ants crawling under the skin of the legs is also frequently described by patients experiencing sciatica. The intensity of the pain varies among the patients. Some individuals experience excruciating debilitating pain that causes them to become bedridden for a couple of days, while others have only mild pain in their back and legs. While the sciatic pain usually starts in the low back and continues down the leg along the path of the sciatic nerve, the pain is usually more intense in the legs than in the back. Sciatica generally affects only one leg at a time. It is rare to see the involvement of both legs at the same time. If this is the case, it is important to seek medical evaluation to rule out other causes for these symptoms.
There are many reasons why someone may develop sciatica. The risk factors are similar to developing any back pain. The excessive weight which creates too much pressure on the spine, sedentary occupation with lack of movement or carrying heavy objects are some of the most important causes. Aging is an independent factor that compounds any of the above risk factors because most people become more sedentary as they get older, gain weight and become less flexible. Sciatica is however not exclusive of young healthy individuals. Many individuals in the 30s present to their health care provider’s office with symptoms of sciatica after sustaining injury from doing exercises at the gym. This is usually related to lifting heavy weights, not stretching before and after exercising, as well as not getting enough rest to allow body fully recover and regenerate. To prevent flare-ups of sciatica it is, therefore, crucial to maintaining healthy weight and stay mobile.
While sciatica can be rarely caused by a bone spur or a tumor, in most cases of sudden onset of sciatica, it is related to a disc herniation. The treatment for sciatica is therefore essentially the same as for disc herniation since both share the same underlying cause. Treatment guidelines for disc herniation can be found here.

People affected by spinal stenosis may experience a variety of symptoms. Some individuals may have no symptoms at all, especially in the initial stages, while others may experience significant amount of pain. It is not known why some people experience more or less pain. Spinal stenosis is a degenerative disease and therefore develops slowly over period of time with gradually worsening symptoms. Most individuals experience tingling and numbness in their buttocks, legs, and calves, especially after prolonged walking. Walking up the hill or up the stairs is particularly painful, but even walking down the stairs can lead to significant amount of pain. In more advanced cases, weakness of the legs, pain, and cramping in one or both legs and feet can present with prolonged standing or walking. In severe cases, an individual may not be able to walk more than few blocks before severe pain develops.
There are several reasons why spinal stenosis may develop. The most common causes include osteoarthritis and bone spurs. Osteoarthritis is one of the forms of arthritis. It is a result of wear and tear that affect the protective cartilage on the ends of the bones. When osteoarthritis is present in the spine, it can cause over time narrowing of the spinal canal, which eventually results in spinal stenosis. When bone spurs develop as a result of long term wear and tear, the spurs may grow inside of the spinal canal and cause pressure on the spinal nerves. Less frequent causes of spinal stenosis include a spinal tumor and a car accident. In both of these cases, there are usually several other prominent symptoms that point out to that diagnosis.
In mild cases of spinal stenosis, a conservative treatment approach is recommended. This may consist of physical therapy and strength training, stretching, short term course of acupuncture, daily stretching, swimming, Tai Chi or Yoga exercises. The goal is to keep the back muscle flexible and relaxed as much as possible. Building core strength is also important to properly distribute the weight and decrease the load on the spine. Losing excessive weight is crucial for the successful management of back pain. Carrying less weight translates to less pressure on the lumbar area of the spine from the excessive forward pull of the abdomen.
In more severe cases when the benefits of conservative treatment have been maximized, but pain continues to significantly affect the quality of life, surgery may be necessary. This should be however the last resort since there are inherent risks to any surgical procedure. It has been recommended, that only when all other treatment options have been exhausted, and the individual’s quality of life as it is now is poor, surgery should be considered as a possibility to improve current quality of life.

When the facet joints become inflamed because of injury or arthritis, they will generate pain. Acute presentation of facet joint pain may resemble those caused by a herniated disc and at this stage it may be difficult to differentiate between these two. In most case the individual can pinpoint the area of pain indicating involved facet joint. At time, however, the person may experience diffused poorly localized pain in the lower back, hips, and buttocks on both sides. Most patients presenting with pain due to facet joint inflammation have difficulty bending backward which may help to establish the diagnosis. In some cases, the facet joint pain may project pain down to the legs and mimic the sciatic pain. Unlike sciatica, where the pain may project all the way down to the feet, facet joint pain usually terminates at the level of the knees. Only in rare cases the pain may project all the way down to the feet. This is usually seen when osteophyte is causing pressure on the nerve root.
The major cause for the development of facet joint syndrome appears to be osteoarthritis of the facet joints. Osteoarthritis is generally a consequence of wear and tear. It is characterized by narrowing of joint spaces, loss of joint cartilage and local joint inflammation. This process is similar to the more familiar knee osteoarthritis which is a well-known cause of knee pain among the elderly population. It has been shown that younger individuals suffering from facet joint syndrome tend to have history of strenuous jobs prior to the age of 20 which puts them at high risk for early osteoarthritis of the facet joints.
Inflammation of the facet joints is generally not well diagnosed by MRI or X-Rays. There is also a poor correlation between the findings on the images, physical exam by the provider and the symptoms that the patient experiences. In most cases injection of an anesthetic medication into the vicinity of the painful facet joint can help to make the diagnosis. If the patient experiences immediate pain relief after the injection, the condition can be diagnosed as facet joint syndrome and steroid injections can then be administered to decrease the local inflammation. The steroid injections are usually administered by pain specialists under fluoroscopy which helps to guide the needle placement. The patient may receive these injections every 3-6 months based on the duration of symptoms relief.
Acupuncture treatment can also be beneficial since needling the musculature in the affected area can improve local blood circulation and decrease the inflammation and muscle tension. Referral to physical therapy to learn appropriate core strengthening and stretching exercise is important in long term management and prevention of further exacerbation.
Cure or management of chronic back pain?
When discussing the treatment of chronic back pain, it is important to understand, that there is no reliable “cure” for chronic back pain. That is not to say that once an individual develops chronic back pain, they will have to suffer from the pain for the rest of their life. In fact, most chronic back pain can be successfully managed, to allow the individual to live a normal productive life. It should be understood, however, that the nature of chronic back pain is fluctuating periods of no pain or only minimal discomfort with periods of severe worsening of back pain. These fluctuations generally correspond to the demands of daily life. It is usually not possible to completely avoid the periods of more intense back pain. The frequency and the severity of these episodes can be, however, controlled to a large extent. Conscientious adherence to daily routine which includes specific exercises, stretching and self-acupressure, along with minimizing the exposure to activities that pose undue stress on the back, has been shown to significantly reduce the episodes of worsening back pain.
Common treatment modalities
Numerous treatment options have been developed for the treatment of back pain. They range from conservative noninvasive options, which can be applied by an individual at home, to more invasive treatments requiring a visit to a health care provider. In extreme cases, surgical intervention may be necessary.
Self-acupressure can be applied to the specific trigger points in the affected musculature by the patient at home on daily bases. It can be used as a sole treatment for the management of mild to moderate back pain. Self-acupressure can be also used along with any other modality to reinforce the treatment effect and promote faster recovery. More information about acupressure can be found by clicking on the tab on the left-hand side of this page.
Physical Therapy
Physical therapy is frequently used as a part of an overall treatment protocol to treat acute or chronic back pain. The goal of physical therapy is to relieve pain, help the body in the healing process, and restore normal functional pain-free movement. A physical therapist can prescribe specific rehabilitation exercises alone or in combination with dry needling, TENS, heat application, soft tissue release or gentle manipulations. Physical therapy is generally initiated if the injury is not spontaneously recovering with conservative treatments within 2-6 weeks. In case of severe acute back pain, however, a referral to physical therapy can be initiated right away. For more information click on the tab on the left-hand side.
Acupuncture and dry needling are both very safe therapeutic modalities. Dry needling is mostly available to the patients through the department of physical therapy. The carefully selected patients which may benefit from dry needling usually receive a series of dry needling sessions as part of their physical therapy treatment plan. There are some primary care providers who have been trained in dry needling. They may offer this treatment modality to their patients on limited bases given their busy schedule. Acupuncture is available to patients only from licensed acupuncturists or physicians with training in medical acupuncture.

Pharmacologic management
Pain medications play an important role in the management of chronic back pain for many patients. Some patients rely on a daily dose of pain medication to control their pain and there is a definite role for pain medication in the management of chronic pain. It is important to point out, however, that the medication should not be relied on as the sole long term strategy to keep chronic pain under control. This passive approach generally leads to further deconditioning, the need for increasing the dosages of medication and inherently to more side effects associated with their daily use. Appropriate use of pain medication can be, however, an integral part of a comprehensive treatment plan when used under the guidance of a qualified health care provider. In general, the pain medication should be used at the minimal effective dose and for the shortest amount of time, unless directed otherwise by the health care provider.
No surgical procedure is risks free. Formation of scar tissue and the need for subsequent surgery are known complications. Surgery should be therefore reserved only for rare cases. These generally include instances where all other treatment options have been exhausted. In these cases either the pain cannot be successfully controlled by any other intervention or there is a significant functional deficit that can be improved by the surgical procedure.

Many patients frequently complain that physical therapy has not worked for them. They refuse to follow up with the referral made by their provider and demand Xrays or MRIs to find out why their back continues to hurt. While X-ray or MRI is not necessary in the majority of chronic or acute back pain, physical therapists frequently order these studies if the patient's condition is not responding to the treatment protocol. Imaging studies can also be ordered if the physical therapist feels that it will help them create a more specific treatment plan. Imaging studies, however do not cure back pain. It is critical to realize that any treatment modality only works if the patient is an active participant. When it comes to physical therapy, the reality is that most patients are not compliant with the prescribed treatment plan. It is not enough to come to physical therapy once or twice a week for half an hr session and expect to see major improvements. Adherence to prescribed exercise at home as instructed by the physical therapist is the key. Physical therapy sessions at the clinic should be used primarily as an opportunity to assure the correct form and assess the progress. To get the most from physical therapy, the majority of work has to be done at home.
Key factors in the treatment of chronic back pain
While most acute back pain eventually resolves on its own, chronic back pain tends to fluctuate between days with more or less pain. To increase the number of days without pain or with only slight discomfort, something fundamental has to change. There are many factors that impact the successful treatment of back pain. Two of the most important factors are elimination of aggravating factors and correcting muscle imbalance. Physical therapists are medical professionals with extensive training in skeletomuscular disorders and thus best suited to help patients accomplish both.
Physical therapists can review with patients their daily routine and help them identify the major aggravating factors that continue to flare up their back pain or prevent the maximal recovery. They will thoroughly asses the patient’s condition and create an individual exercise treatment plan. Physical therapists can help the patient tailor a specific work out routine that will help them achieve their personal fitness goals without aggravating their back pain. Additionally, physical therapists are the top authority to teach patients the correct execution of individual exercises to prevent future injuries. Incorrectly performed exercises continue to be the leading cause of many exercise-related injuries. Incorrectly performed exercises can lead to permanent joint or back injury.
Summary
Physical therapy is an integral part of any comprehensive treatment approach to chronic back pain. In some cases, physical therapy can be, however, beneficial also in acute cases of back pain. Physical therapists often incorporate variety of techniques and tools when designing their individual treatment plan. Imaging is usually not needed in most cases of uncomplicated chronic and acute back pain but imaging studies can be ordered by the physical therapist if it is indicated. Physical therapists are top experts in designing individual workout routines that will help patients achieve their fitness goals without risking further injuries. Lastly, physical therapy only works if patients become active participants.
A trigger point is usually defined in textbooks as a painful point that can be felt as a hard nodule in the muscle. Clinically, however, a trigger point is more of an area of the muscle, not necessarily a precise point. There may be a palpable nodule, but that is not always the case. A better definition of a trigger point is an area of muscle that feels tight and ropy and usually is tender on palpation. Not every tender area within a muscle, however, is a trigger point. Several other characteristics have to be present for a tender area of the muscle to meet the criteria for the definition of a trigger point. Trigger points are therefore usually defined as areas that are tender on palpation, but also display twitch response when strumming the tight muscle band in a perpendicular direction. Compression of the trigger point also needs to reproduce the patient’s familiar pain. In some cases, when pressure is applied to the trigger point, the pain can be felt in a distant area of the body. This phenomenon is known as referred pain. The typical example of referred pain secondary to trigger points is pain at the base of the spine or the buttock, caused by trigger points in the mid-back muscles, at the area of the lowest ribs. A new definition of trigger points, however, suggests that referral of the pain to the distal area of the body does not need to be present in order to make the diagnosis of a trigger point.
When a muscle or a group of muscles is subject to repetitive overuse or sudden strain, a contraction will form in a small number of muscle fibers within the affected muscle. We refer to these small contractions as trigger points. The presence of trigger points in the muscle, shortens the length of the muscle, much like making series of knots on a piece of a string. The more knots on the string, the shorter and tighter the string becomes. This analogy can be applied to muscles that become tight due to the presence of trigger points. The shorter the muscle becomes, the more distinct ropy feeling can be appreciated when strumming perpendicularly across the affected muscle. When a muscle becomes shorter because of the trigger points, it will start to generate greater pull on the tendons and ligaments that attach the muscle to the joints and other structures. In the case of the knee joint for example, if trigger points are present in the quad muscles, they will shorten the quad muscles. The quad muscles attach below the knee through a tendon that runs over the kneecap (patella). The shortness in the quad muscles will therefore cause the kneecap (patella) to be compressed over the underlying cartilage whenever the knee is flexed. Greater friction between the patella and the underlying cartilage will over time result in faster loss of the underlying cartilage or formation of inflammation. This condition is called a chondromalacia patella and is experienced by the individual as a deep achy pain underneath the kneecap.
In general, trigger points tend to form in the muscle that is subject to a higher load than the muscle can tolerate. There are a variety of factors that have been noted as potential causes for the development of trigger points. The most significant of these include acute or chronic muscle overload due to poor posture or over-exercising. Direct trauma to the muscle, as well as trauma due to a car accident which leads to a whiplash, are another common cause for developing trigger points. Additionally, psychological distress, homeostatic imbalances, and certain lifestyle habits such as smoking, have been identified as important contributors to the formation of trigger points. When an area of muscle is constantly overloaded, the resulting muscle tightness in that area will compress the surrounding blood vessels. This leads to poor local blood circulation with subsequent accumulation of various metabolic by-products and chemicals which sensitize the surrounding nerve endings. The impaired metabolism and blood circulation in the muscle further impair the muscle’s ability to fully relax. Eventually, the muscle develops sustained contraction leading to the development of palpable tight and ropy areas of the muscle defined as trigger points.
Decreased athletic performance
When muscles develop trigger points, their overall capacity to do their job is impaired. Physiologically, the basic function of the muscle is to expand and contract. The presence of the trigger points causes the muscle to assume a constant shortened and contracted state, hindering the muscle’s ability to fully flex and contract. This will manifest as overall muscle weakness, decreased range of motion, feeling of stiffness, earlier fatigue, and intolerance to high-intensity workload. Muscles that have trigger points also recover much slower. The combination of all these factors interferes with athletic performance and leads to suboptimal results despite adequate training and preparation.
The characteristic feature of trigger points is their ability to refer pain to distal areas of the body, which makes the correct diagnosis of the true origin of the pain challenge. Detailed pain referral pathways have been described for individual muscles and their trigger points. These referral pathways sometimes overlap, therefore a detailed search of all muscles which can refer pain to a particular area, should be conducted, to identify all the sources of the pain. An example of referred pain to the same area from a different muscle is a pain in a pinky and along the inner aspect of the hand. This referral pattern is typical for trigger points in the Latissimus dorsi. In some cases, however, the pain in the pinky and along the inner aspect of the hand can result also from the presence of trigger points in the Infraspinatus muscle.
Several non invasive treatment options are available to address and treat trigger points. Some of the most popular include acupuncture, dry needling and acupressure modalities. Follow these links to learn more about each one of the them.
