Treatment. Ganglion cysts often clear up on their own spontaneously and do not need treatment, especially if there is no pain and the cyst does not interfere with normal activities. When treatment is advised, non-surgical treatments may be used such as anti-inflammatory medication and a splint. Immobilization with a splint or brace can relieve symptoms and help the cyst decrease in size. Aspiration can be done to drain the fluid and decompress the cyst. This is usually recommended when the cyst is painful or limits movement. When non-surgical options fail, surgical removal of the cyst and a part of the tendon sheath or joint capsule may be used. Cysts may return, even after surgery.
