Bursitis of the deltoid muscle is an aseptic inflammatory disease that can be caused by local strain, trauma, and cold. The treatment can be conservative, requiring the patient to reduce weight-bearing activities in the shoulder joint area and to keep warm. In the deltoid area, acupuncture and moxibustion can be used, and the application of small needle knife to pry and loosen the bursa can accelerate the absorption of the bursa and reduce the leakage of bursa fluid. You can also use hot towel compress, physiotherapy instrument baking, microwave instrument treatment or choose orthopedic wash medicine to give local fumigation. If the patient’s pain is obvious, local closed injection or oral ibuprofen extended-release tablets or diclofenac sodium capsules can be given to the bursal area for treatment.
