The incidence of cysts in the muscle is relatively low and they usually do not subside on their own. For smaller cysts in the muscle, conservative treatment can be considered, or you can go to the hospital and have the cyst fluid extracted by puncture, inject sodium hyaluronate injection etc. into the area, and then apply pressure bandages. However, it should be noted that this conservative treatment has a very high recurrence rate. For patients with poor treatment results and recurrent attacks, surgical removal of the cysts can be considered. The cause of the disease is not clinically clear and may be related to chronic strain injury, usually seen in typists or porters. If larger muscle cysts are found, early surgical treatment is recommended to avoid affecting the function of the limb.
