Subacromial bursitis can be cured on its own if the duration of the disease is short and you pay attention to rest. If the course of the disease is long and the recurrent subacromial bursitis is difficult to be cured by itself, it can be treated by physical therapy, medicine and surgery. Subacromial bursitis is an aseptic inflammation of the subacromial bursa due to proliferation and exudation of the subacromial bursa as a result of repeated impingement of the acromion and humeral head. If the onset of the disease is relatively short, pay attention to appropriate rest, while avoiding cold, most of the 4 to 6 weeks can be self-healing. If there is no formal and effective treatment, the disease duration is long, and the inflammation of subacromial bursa is recurrent, it can be treated by shoulder braking, resting and physical therapy such as hot compresses, massages, massage, etc., and taking non-steroidal anti-inflammatory and analgesic drugs such as nimesulide and diclofenac sodium to relieve the pain. If the disease cannot be cured after conservative treatment, it can be completely cured by arthroscopic surgery to remove the diseased bursa. If subacromial bursitis is identified, regular rehabilitation or treatment under the guidance of a physician is recommended.
