Foreign epidemiological studies have found that 93% of outpatients with pain are associated with myofasciitis, and myofasciitis is the sole cause in 75% of patients. Myofasciitis is a non-infectious inflammatory reaction of skeletal muscle. The basic pathology is edema, exudation and fibrous changes in myofascial and muscle tissue, resulting in a series of clinical symptoms. It is a non-specific change of the body’s rich white fibrous tissue, such as fascia, myofascia, ligaments, tendons, tendon sheaths, periosteum and subcutaneous tissue. It is a clinically common, yet often overlooked or misdiagnosed pain condition. For example, sternocleidomastoid fasciitis is often misdiagnosed as headache, or even as Meniere’s syndrome, or even cerebral neuropathy. Skeletal muscles account for approximately 50% of the body’s weight, and with approximately 400 skeletal muscles throughout the body, the most significant symptom caused by myofasciitis is pain. Myofasciitis pain syndrome is the cause of most pain. It is also known as myofibrositis and is the leading cause of chronic muscle pain. Etiology: The causes of myofasciitis are multifaceted. Wet and cold climates are one of the most common causes. Wet and cold can cause muscle vasoconstriction, ischemia, edema causing local fiber plasma exudation and eventually fibrofibrillitis. Muscle tension, strains, chronic injuries to specific muscles in some special positions and other chronic strain injury is another important factor in its pathogenesis, muscle, fascia damage occurs after fibrotic changes, so that the soft tissue in a state of high tension. This results in a small tearing injury, which eventually leads to an increase in fibrous-like tissue and contraction, squeezing the local capillaries and peripheral nerves to appear painful. Other causes such as viral infection and muscle metamorphosis of rheumatism are all triggers. Secondly, the lack of calcium, iron, potassium, vitamin C, B1, B6 and B12 also play a role in the development of myofasciitis. Stroke and paralysis, body deformities, etc. can also lead to chronic strain on the muscles involved in the body, which can cause pain, etc. In addition, chronic infections, depression, sleep disorders, hypothyroidism, and hyperuricemia often complicate myofasciitis. Clinical symptoms: Myofasciitis can cause localized pain, muscle tightness, stiffness, restricted movement, voluntary twitching, etc. It is not fatal, but it makes life very uncomfortable and is a reason for many people to take time off from work. Myofasciitis is a very common condition, and almost all people suffer from varying degrees of myofasciitis throughout their lives. 14.4% of the U.S. population has regular skeletal muscle pain, and much of it is caused by myofasciitis. There is no difference in the prevalence of myofasciitis between men and women, and there is no clear age limit; even infants can get the disease. Of course, the likelihood of myofasciitis increases with age, and middle-aged and elderly people are therefore the main contributors to this disease. It has been observed that sedentary people are more likely to develop this disease than those who exercise regularly, especially those who sit hunched over a computer all day. Diagnosis: 1. Local pain, coldness, numbness, muscle spasm and movement disorders. 2. The pain often comes on in the early morning and is relieved or disappears after activity or heat application. 3.There is obvious limited pressure pain. Needle pricking or pressure on the agonizing point can reproduce the patient’s pain, and sometimes there is distal sensory transmission pain. 4.The pain disappears after injection with needle prick or procaine pain point. When needling or injecting the painful point, local convulsive reaction may occur. Laboratory tests: anti-“O” or blood sedimentation is normal or slightly high. Treatment: For mild patients, it can usually be cured without treatment by removing the cause of the disease and applying local warmth and heat. For moderate to severe cases, acupuncture therapy with painful points is often extremely effective.
