Tendonitis is called tendon pain in Chinese medicine because tendon tissue is collectively called tendons in Chinese medicine, and the scope of tendons in Chinese medicine includes muscles, tendons and other tissues in various parts of the body. The cause of tendon sheathitis is mainly related to strain, long-term use of local joints resulting in inflammatory reactions around the joint tendons, and the accumulation of inflammatory reactions cause local adhesions, scarring, thus affecting the movement of joints, in the analysis of Chinese medicine is the state of qi stagnation and blood stasis. The principle of TCM treatment is to invigorate blood stasis, promote blood circulation and relieve pain, and treat the disease with external Chinese medicine such as Tao Hong Si Wu Tang combined with moxibustion and hot compresses, as well as functional exercises for finger joints and acupuncture to unblock the meridians. However, if the duration of tendonitis is too long, for example, more than 1 year with severe dysfunction, finger movement is obviously unfavorable and pain is particularly severe, surgery is recommended.
