The main symptom of intercostal fasciitis is the presence of pain and swelling in the intercostal area with functional impairment, especially in acute episodes, when the pain increases significantly after breathing or strenuous exercise. It may generally be caused by costochondritis or intercostal neuritis, as well as by degeneration of some intervertebral discs, thickening and calcification of joint capsules and ligaments, resulting in narrowing of nerve conduction channels, causing symptoms of irritation of nerve roots and pain at the site of the corresponding intercostal walking nerve, which is more intense and often aggravated by improper rest, exertion and emotional fluctuations. The main principle of treatment of this disease is to actively treat the primary disease, together with some auxiliary microwave physiotherapy methods to promote local and chest blood circulation and reduce inflammatory stimulation. In addition, pay attention to warmth, avoid strenuous exercise, and adjust the body posture appropriately to minimize the symptoms of intercostal nerve irritation, and through dietary regulation, physical therapy, and the application of drugs, intercostal neurofasciitis can be completely cured.
