What is muscle pain (myalgia, myofascial pain syndrome)?
Myofascial pain syndrome is characterized by muscle pain, tenderness, and spasm. Myofascial pain syndrome usually involves muscles in body areas that are asymmetric or focal, whereas fibromyalgia is typically a diffuse and symmetric muscle pain syndrome that involves both sides of the body.
What muscles are affected by myofascial pain syndrome?
Myofascial pain syndrome causes localized muscle pain. Affected muscles cause the following:
- neck pain,
- upper back pain, and
- lower back pain, generally affecting one side of the body or one side of the body much more than the other.
- There is commonly tenderness and spasms in the painful areas and there may be tenderness in areas that are not feeling chronic pain.
It is also common for patients with myofascial pain syndrome to have poor sleep patterns with decreased recovery sleep (non-rapid-eye movement sleep). This is associated with awakening feeling unrested and daytime fatigue. Stiffness after inactivity is common.
What causes myofascial pain syndrome?
The cause of myofascial pain syndrome is unknown. Nevertheless, prior injury, poor sleep patterns, stressful life situations, and depression are common underlying conditions that may play a role in inciting and exacerbating myofascial pain syndrome. It is currently felt that risk factors such as these may lead to a change in the ability of the brain to properly process pain perception (referred to as central pain processing).
Myofascial pain may develop from a muscle injury or excessive strain on a particular muscle or muscle group, ligament, or tendon.
Other causes of myofascial pain syndrome include:
Diagnosis of myofascial pain syndrome
Myofascial pain syndrome is commonly treated by primary-care physicians, including family medicine doctors, general practitioners, and internists. Other physicians who treat myofascial pain syndrome include physiatrists, orthopedists, and rheumatologists.
Physicians diagnose myofascial pain syndrome based on the areas of complaints of muscle pain and associated tenderness during a physical examination. Extensive laboratory testing is usually unnecessary. There are no apparent changes (redness, warmth, swelling, etc.) in areas of involvement. The appearance is the same as similar areas on the other side of the body. The widespread, diffuse body involvement that is typical of fibromyalgia is not present.
What is the treatment for myofascial pain syndrome?
Optimal treatment of myofascial pain syndrome can be a multifaceted approach. This can include education of the patient and the following:
- stress reduction,
- stretching and exercise programs as well as physical therapy rehabilitation,
- sleep improvement, and
- medications all best organized by a single physician who tailors the therapies over time by customizing them for the individual patient.
Medications used to treat myofascial pain syndrome can be directed toward various features of the individual's condition and may be used temporarily or long-term. Often trials of medications are used to find the best treatment for a particular patient. For example, trazodone (Serzone) or amitriptyline (Elavil) may be used at bedtime to improve sleep as well as relieve pain; cyclobenzaprine (Flexeril) or orphenadrine (Norflex) can be used at bedtime to relax muscles and to aid sleep; and antidepressants such as sertraline (Zoloft), fluoxetine (Prozac), duloxetine (Cymbalta) can be used to help control pain as can gabapentin (Neurontin) and pregabalin (Lyrica).
Home remedies for myofascial pain syndrome include:
- hot water soaks, and
What is the prognosis for myofascial pain syndrome?
Myofascial pain syndrome can resolve with ideal treatment regimens. However, many patients with myofascial pain syndrome have had symptoms for years. Outcomes are best when a multifaceted treatment approach is guided by a single physician who is monitoring the response to various therapies employed.
What are the complications of myofascial pain syndrome?
Myofascial pain syndrome can lead to several complications if left untreated, such as:
Because of the potentially life-altering consequences of MPS, it is important to seek medical attention to manage symptoms and seek proper treatment.

Low Potassium (Hypokalemia)
Potassium is an essential electrolyte necessary for cell function. Low potassium (hypokalemia) may be caused by diarrhea, vomiting, ileostomy, colon polyps, laxative use, diuretics, elevated corticosteroid levels, renal artery stenosis, and renal tubular acidosis, or other medications. Symptoms of low potassium include weakness, aches, and cramps of the muscles. Treatment is dependent upon the cause of the low potassium (hypokalemia).
Muscle CrampsMuscle cramps are involuntarily and forcibly contracted muscles that do not relax. Extremely common, any muscles that have voluntary control, including some organs, are subject to cramp.

A massage is a therapeutic manipulation of soft tissue of the body with the goal of achieving normalization of those tissues. A traction refers to the practice of slowly and gently pulling on a fractured or dislocated body part. It is usually performed by a medical professional such as a physiotherapist, using ropes, pulleys, and weights. Manipulation is the use of the hands by a professional on the patient by using specific techniques and maneuvers to achieve painless movement and right posture of the musculoskeletal system.
