Postpartum rheumatism is also known as postpartum arthralgia, and belongs to "arthralgia syndrome" in traditional Chinese medicine diagnosis. It is one of the diseases with high incidence in puerperal period. The course of the disease is as short as a few days to several days, and as long as it lasts, it will not heal for many years and will persist for many times. Most of the causes are due to puerperal physical weakness or fatigue and injury, and recurrent wind, cold and dampness. Clinical manifestations are mainly pain, swelling, numbness and stiffness of single joint or multiple joints, Accompanied by morning stiffness, fatigue, aversion to wind, aversion to cold and other concurrent syndromes, the disease can be aggravated when the weather changes. Because the physical and chemical examination results of western medicine for patients with this disease are mostly negative, doctors and patients do not attach much importance to it. However, the patients suffer unbearable pain, and there is no ideal treatment plan except anti-inflammatory and analgesic in western medicine. Therefore, traditional Chinese medicine is the main treatment in clinic. However, due to lactation and other reasons, the application of oral drugs such as traditional Chinese medicine decoction is limited to a certain extent, and patients are more accepting external treatment for postpartum rheumatism. For the middle-aged and elderly patients with long course of postpartum rheumatism, even reaching several decades, some patients take drugs orally all the year round, mostly accompanied by gastrointestinal discomfort symptoms, and are unwilling to take drugs orally. Traditional Chinese medicine external therapy has become their first choice. Such as herbal sticking method, Steam therapy, warm acupuncture, adding drugs moxibustion and other external treatment methods. They are respectively suitable for patients with different syndromes and characteristics, and can be treated according to syndrome differentiation and symptomatic application just like soup medicine, Not only has obvious curative effect and can quickly relieve the pain of patients, but also has little side effects such as no influence on lactation, gastrointestinal stimulation and the like. Postpartum breast-feeding population and patients with longer course of disease are more acceptable.
