Periarthritis of the shoulder generally refers to the aseptic inflammation around the shoulder joint, which is common in middle-aged and elderly women. It is caused by chronic strain of the shoulder joint, affecting the surrounding muscles, tendons, joint capsules, and ligaments. First, it is important to rest and you can promote blood circulation around the area with appropriate physiotherapy, such as hot compresses and acupuncture, to facilitate the repair of the damaged area. At the same time, appropriate exercise should be carried out to avoid stiffness of the joint that can occur with prolonged immobility or passive restraint.
