Tendinitis of the thumb can be treated by physical therapy, medication and surgery. 1. Physical therapy: patients can use massage, hot compresses and other ways to promote local blood circulation, relieve pain and promote the elimination of inflammation. 2. Drug treatment: patients can use non-steroidal anti-inflammatory drugs such as celecoxib to eliminate inflammation and achieve therapeutic effect. 3. Surgery: If medication is not effective, surgery is needed. Patients can choose appropriate surgery, such as tenotomy and decompression surgery for treatment. All of the above treatments should be used under the guidance of a physician. If the patient has tendovaginitis of the thumb and cannot relieve it by himself, he should go to the hospital in time for treatment.
