Finger tenosynovitis can be treated conservatively if the symptoms are mild in the early stage of the disease, or surgically if the symptoms are severe over a long period of time. Finger tenosynovitis can be treated conservatively if the pain is mild and the limitation of activity is not obvious in the early stage of the disease. For example, pay attention to rest and avoid manual labor. Scald your hands with hot water, and then gently massage the tenosynovitis area to promote blood circulation and promote the absorption of inflammatory substances. Oral anti-inflammatory and analgesic drugs such as nimesulide and diclofenac sodium can also be taken for treatment. For those who still can not be completely improved after the above treatment, you can also use lidocaine mixed with compound betamethasone to do intratendon sheath closure treatment. If the tendovaginitis is of long duration and the thickening of the tendon sheath will compress the tendon, limiting the movement of the fingers and causing severe pain, surgery can be used to cure the tendovaginitis by cutting the thickened tendon sheath and partially removing the thickened tendon sheath. If the symptoms of tenosynovitis appear, it is recommended that the patient go to the hospital, complete the examination, and carry out regular treatment. The use of medication should be in accordance with medical advice.
