Fasciitis, also known as fibrous tissue inflammation, can occur in various locations throughout the body. The striated, punctate nodules often felt at the location of the provocation point are essentially a confined fibrous connective tissue. In some patients, small nodules may be palpated on the surface portion of the body, and such nodules may stimulate peripheral nerve endings to produce localized muscle spasm and pain. Because many patients with fasciitis do not receive proper and thorough treatment during the acute phase and turn to chronic pain, or repeated adverse stimuli such as strain and wind chill, symptoms such as persistent or intermittent chronic muscle pain, soreness and weakness occur. Fasciitis is an aseptic inflammatory reaction of the muscles and fascia. When the body is stimulated by external factors such as infection, fatigue, trauma or improper sleep position, the acute onset of myofasciitis can be triggered, and fibrotic changes occur after damage to the fascia. The clinical manifestations are mostly painful, mostly soreness and discomfort, muscle stiffness and stagnation, or a feeling of heavy pressure, and sometimes painful nodules or painful muscle cords can be palpated under the skin. Wang Mingjie said some patients with fasciitis have increased symptoms in the morning or after weather changes and cold, and the pain is relieved after activity, often with recurrent attacks, which need to be distinguished from rheumatic diseases. In acute attacks, the local muscles are tense and spastic, and movement is limited. Fasciitis can be divided into the following categories: 1. Neck and shoulder myofasciitis Extensive pain and heaviness, numbness, stiffness, limited movement and weakness in the back of the neck and shoulder, which can be dissipated to the back of the head and upper arm. The pain is persistent and can be aggravated by infection, fatigue, cold, and moisture. The disease has a slow onset and a long duration. 2, low back myofasciitis is a series of clinical symptoms that occur due to edema, exudation and fibrous changes in the myofascia and muscle tissue of the low back caused by cold, humidity and chronic strain. It is a non-specific change of the body’s rich white fibrous tissues, such as fascia, myofascia, ligaments, tendons, tendon sheaths, periosteum and subcutaneous tissues. 3, plantar fasciitis is caused by aseptic inflammation of the tendons or fascia of the sole of the foot. The most common symptom is pain and discomfort in the heel, pressure points are often on the bottom of the foot near the heel, and sometimes the pressure pain is more intense and persistent. In general, the pain is most pronounced in the first step when getting out of bed in the morning, mainly because after a night’s rest, the plantar fascia is no longer weight-bearing and will be in a shorter state. Thus, when getting out of bed and stepping on the ground in the morning, there will be a larger and faster pull on the plantar fascia, which will cause pain. However, after walking for a period of time, the plantar fascia becomes looser and the symptoms are relieved. The pain increases with excessive walking, and in severe cases, the pain is felt even when standing and resting. Plantar fasciitis is a chronic injury caused by exercise. Overtraining can also cause pain in the heel bone, sometimes radiating to the front of the foot, and this disease can affect adults of all ages. 4, eosinophilic fasciitis Eosinophilic fasciitis refers to a connective tissue disease involving the deep fascia of the limb skin with scleroderma-like manifestations, which is less common clinically. The main manifestations are sudden onset of lesions, scleroderma-like skin lesions, significant increase in peripheral blood eosinophils, inflammation of the fascia with eosinophil infiltration on skin histopathology, and no significant changes in the epidermis and dermis. 5, nodular fasciitis is a reactive, self-limiting nodular fibroblastic proliferative lesion of the superficial fascia, also known as pseudosarcomatous fasciitis. The cause is unknown, and most patients have a history of trauma, which may be related to trauma or infection. Nodular fasciitis is a non-neoplastic lesion that is better removed surgically and may disappear on its own in a few patients. 6. Necrotizing fasciitis is a soft tissue infection characterized by extensive and rapid subcutaneous tissue and fascial necrosis, often accompanied by systemic toxic shock. The disease is a mixed infection with a variety of bacteria, mainly aerobic bacteria such as Streptococcus pyogenes and Staphylococcus aureus. The infection only damages the subcutaneous tissue and fascia, and does not involve the muscle tissue at the site of infection is its important feature. Treatment of the disease has a good prognosis. For patients with acute exacerbations, hormones combined with nonsteroidal anti-inflammatory drugs and antirheumatic drugs for palliation can be used. After the disease is controlled, hormones can be reduced and discontinued in some patients.
