The so-called periarthritis of the shoulder is often caused by prolonged excessive stretching and irritation around the shoulder, external injuries, or exposure to cold, leading to aseptic inflammation in the shoulder area. Patients typically exhibit significant pain symptoms in the shoulder area, and in severe cases, it can cause local muscle atrophy and joint stiffness, which are characteristic of periarthritis of the shoulder. For the treatment of periarthritis, conservative measures can be actively pursued, such as applying topical ointments that invigorate the blood and dispel stasis, taking oral non-steroidal anti-inflammatory and analgesic medications, and medications that invigorate the blood and dispel stasis. Small needle knife surgery can also be considered. Activities like wall climbing can be performed to exercise the mobility of the shoulder joint. (Note: The use of medications should be under the guidance of a professional doctor.)
