The treatment methods for arm pain and limited movement are local physical therapy, massage, infrared irradiation, microwave therapy, silver needle therapy, and closed therapy, all of which can bring significant relief. The main cause of pain and limited movement is due to chronic strain of muscles, fascia and tendons. In the upper arm, pain caused by aseptic inflammation due to biceps longus tendonitis is more likely to occur, and in the forearm, pain caused by aseptic inflammation due to epicondylitis of the humerus is the main cause. Both diseases are usually caused by aseptic inflammation due to chronic strain, which leads to local edema, adhesions, hyperplasia, and even calcification, causing limitation of movement. With active treatment, both will be significantly relieved and cured.
