Heat application can play a certain role in improving the symptoms of tenosynovitis. You can use a hot towel or a hot water bottle and apply it to the affected area for about 10 to 20 minutes at a time, and you can apply heat several times a day. Be careful to avoid burns during heat application. Heat helps promote circulation and can help reduce the symptoms of tenosynovitis and promote recovery. At the same time, patients should also rest and stop any frequent activities. In addition, they can use anti-inflammatory pain relievers and drugs that promote blood circulation and remove blood stasis, along with physical therapy, injections, and other treatments to improve symptoms and aid recovery. When there is an impairment of movement, surgical treatment can also be considered. (Please use medication under the guidance of a doctor.)
