In general, wrist rattling and pain may be due to wrist strain, tenosynovitis, articular cartilage damage and other reasons. 1. Wrist joint strain: excessive activity of the wrist joint may lead to wear and tear of the joint, which may cause damage to the muscles and ligaments around the joint, resulting in rattling and pain during activities. 2. Tenosynovitis: If the patient has tenosynovitis in the wrist, the friction between the tendon sheath and the tissues will also cause abnormal noise and pain. 3. Articular cartilage injury: Trauma or strenuous activities may lead to tearing of the articular cartilage of the wrist, which may make the joint less stable and cause abnormal noise and pain during activities. In addition to the above reasons, it may also be due to wrist fracture, osteoarthritis of the wrist and rheumatoid arthritis. If your wrist is still painful, you should go to the hospital in time and be treated under the guidance of your doctor.
