Tendon sheath cysts can be treated with hot compresses, which help to relieve the pain, but have no therapeutic effect on the disease itself. Tendon sheath cysts can cause a slow-growing swelling on the dorsum of the wrist, radial wrist flexor tendon, dorsum of the foot, and metacarpophalangeal joints of the fingers, etc. As the swelling grows, symptoms such as soreness, swelling, and pressure pain can occur. Hot compresses can help promote local blood circulation and reduce soreness and swelling. However, hot compresses have no therapeutic effect on the disease itself and cannot destroy the cystic structure that has already appeared to eliminate the cyst. Tendon sheath cysts need to be treated by a doctor by puncture, using a thick needle to drain the contents, followed by an injection of drugs such as prednisolone acetate and a pressure bandage, but they may recur. If it recurs several times, it can be surgically removed. If it is a tendon sheath cyst of the finger, the cyst needs to be removed completely. In the case of tendon sheaths, it is necessary to remove part of the attached tendon sheath at the same time. Patients are advised to seek medical advice and treatment under the supervision of a doctor, and not to squeeze or pinch themselves. The use of medication should be in accordance with the doctor’s instructions.
