First of all, it must be affirmed that patients with tenosynovitis need to actively apply heat. The condition known as tenosynovitis is mainly caused by local excessive irritation and friction, leading to the proliferation of connective tissue and resulting in aseptic inflammation. Therefore, active heat application is necessary. The main purpose of heat application is to promote local blood circulation and the absorption of inflammatory exudates, which can effectively alleviate the clinical symptoms of the patient's tenosynovitis. Additionally, patients with tenosynovitis need to actively rest and protect the affected area. For those with severe pain, local injection treatment can also be considered.
