There are various treatment methods for tenosynovitis, mainly based on the severity of the patient's condition. If the tenosynovitis is very severe, such as the occurrence of triggering or local limb flexion and extension limitations, it is necessary to actively pursue surgical treatment. The surgery can be performed under local anesthesia, typically involving either cutting open the tendon sheath or partially removing it. Post-surgery, it is crucial to actively engage in functional exercises, change dressings, and disinfect the wound to prevent infection. For less severe tenosynovitis, local injection treatments can be an option. Additionally, persistently applying local heat treatments daily can help alleviate symptoms.
