Blocking therapy is a local treatment method for local pain of the body, which is divided into local soft tissue blocking and intra-articular blocking. It is mainly used to treat pain caused by some local aseptic inflammatory reactions of the body, such as periarthritis of shoulder, lateral epicondylitis of humerus, synovitis of knee joint, etc. The drugs used are generally glucocorticoids, such as prednisolone or triamcinolone acetonide, Local injection of pain parts after compatibility with local anesthetics (such as lidocaine) can play a very good anti-inflammatory and analgesic effect. Although the blocking treatment has good effect, there are also some complications, such as long-term use can lead to tendon calcification and tendon rupture. Therefore, the indications of blocking treatment should be strictly controlled clinically.
