About Myofascial Pain
Myofascial pain is a chronic condition that affects the musculoskeletal system, specifically the muscles and fascia. Fascia is the tissue that surrounds organs, blood vessels, bones, nerve fibers and muscles to hold them in place in the body.
Myofascial pain is characterized by muscle tenderness, pain and limited range of motion. The pain is associated with myofascial trigger points, which are tender spots that can produce pain near the trigger point, or in other parts of the body. When pain occurs in another part of the body, it is called referred pain. Common locations of referred pain are the shoulder, back, head and face.
Myofascial pain syndrome is one of the most common forms of chronic musculoskeletal pain, affecting up to 80% of the population. It can be categorized as primary when unrelated to other disorders, or secondary when associated with comorbid medical conditions. The exact mechanisms behind myofascial pain are still not fully understood. Treatment may include exercise, physical therapy, massage, relaxation techniques, and medications.
The pathophysiological causes of myofascial pain syndrome are not fully understood. There may be a relationship to repeated motions used at work or recreation.
Risk factors for developing muscle trigger points and myofascial pain syndrome include:
- Muscle injuries, including car accidents, sports injuries, and ongoing muscle stress from repetitive motion or poor posture.
- Stress and anxiety, which may lead to unconscious muscle clenching.
- Certain medical conditions including hypothyroidism, neuropathy, and vitamin deficiencies.
It's important to note that these risk factors may vary from person to person. It's always best to consult with a healthcare professional for an accurate assessment of your individual risk factors and appropriate management strategies.
Common symptoms of myofascial pain syndrome (MPS) include:
- Localized pain in a specific area, such as the neck and one shoulder. The pain may be aching, throbbing, vice-like, or have a tightness or stiffness quality.
- Tenderness or soreness in muscles.
- Trigger points in the muscles that activate pain. A trigger point may be a small bump or knot in a muscle).
- Muscle weakness.
- Reduced range of motion: Inability to fully move or extend a joint
Other symptoms that may occur include:
- Fatigue (feeling very tired)
- Difficulty sleeping
- Headaches
- Feeling anxious or stressed
It's important to note that pain may appear spontaneously without pressure and may even manifest in areas of the body seemingly unrelated to the trigger points. If you experience any of these symptoms, it's advisable to consult with your healthcare professional for an accurate diagnosis and appropriate management. Home remedies or over-the-counter medications may provide temporary relief, but it's best to seek professional guidance for personalized treatment.
To diagnose myofascial pain syndrome, doctors commonly perform the following examinations, tests, and procedures:
- Medical History: The healthcare profession will ask for information about your symptoms and what triggers them, and about your medical history and medications.
- Physical Exam: The doctor will look for postural abnormalities, such as hunching of the shoulders or misalignment of the head with the spine. The doctor will apply gentle pressure to feel for tight bands of muscle that may cause twitches or trigger pain. They may observe you walk or perform activities such as lifting or stretching.
Additional examinations, tests, and procedures may be performed based on initial findings and individual factors. Some tests may be used to identify possible causes of myofascial pain.
- Imaging Tests: X-rays, or ultrasound, CT, or MRI scans may be used to view certain internal structures of the body (such as joints and muscles) to help rule out conditions.
- Laboratory Tests: These may include a complete blood count, serum calcium/phosphorus/alkaline phosphatase levels, serum uric acid, serum creatinine, and phosphokinase levels to investigate possible infections or muscular disorders.
- Electromyography: This assesses muscle function and fatigue.
- Psychologic Evaluation and Psychometric Testing: These may help in diagnosis by connecting symptoms to specific stressors.
Remember to consult with your healthcare professional for a proper diagnosis and to determine the appropriate examinations for your individual situation.
The goals of treatment for myofascial pain syndrome are to alleviate pain, improve functionality, and enhance the overall quality of life. Here are treatment options and how they work towards achieving these goals:
Medications:
- Nonsteroidal anti-inflammatory drugs (NSAIDs) and muscle relaxants can help reduce pain and inflammation in the affected muscles.
Therapies:
- Physical therapy involves stretching exercises and activities to improve posture, increase range of motion, and strengthen muscles.
- Myofascial release is a manual therapy technique that aims to restore the length of the fascia, reduce limitations, and alleviate pain.
- Red light therapy, also known as low-level light therapy or cold therapy, exposes trigger points to near-infrared light, which may promote healing and reduce pain.
- Electrical stimulation involves placing electrodes on the affected muscle to cause rapid contractions, which can help relieve pain.
- Transcutaneous electrical nerve stimulation (TENS) uses low voltage electrical signals to stimulate the painful area and provide pain relief.
Self-care and Health Behavior Changes:
- Posture modification can help reduce strain on muscles and alleviate pain.
- Kinesio taping can provide support to muscles and joints.
Other Treatments:
- Dry needling involves inserting thin needles into and around trigger points to release tension in the muscles.
- Acupuncture uses thin needles inserted into different locations on the body to promote pain relief.
Each of these treatments aims to address different aspects of MPS, such as reducing inflammation, improving muscle function, releasing tension in trigger points, promoting healing, and enhancing overall well-being. Other treatments may be recommended based on individual factors and symptoms. It's important to consult with a healthcare professional to determine the most appropriate treatment approach for individual needs.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
