Hello, I see you are good at treating orthopedic problems. I have a left back pain. The doctor said it was myositis.

Myofascitis refers to a series of clinical symptoms caused by edema, exudation and fibrosis of myofascia and muscle tissue due to cold, humidity and chronic strain. It is a non-specific change of white fiber tissue in the body, such as fascia, muscle membrane, ligament, tendon, tendon sheath, periosteum and subcutaneous tissue. This is a common clinical pain, which is often ignored or misdiagnosed.
