Xian Cao bone pain patch, also called far-infrared joint pain elimination patch, is a kind of hot compress treatment, and local hot water bag, hot towel of hot compress, baking lamp treatment, infrared physical therapy, spectrum instrument treatment and other methods, the effect is basically the same. If the symptoms of local impaired blood circulation, such as local pain, aggravated by cold, can be relieved after getting warm, the effect of using Xian Cao Bone Pain Patch is relatively obvious, mainly because it promotes local blood circulation, makes local blood vessels dilate, promotes the absorption of local inflammation, thus relieving pain. But the location of the pain, if it is in the joint location, especially the larger joints like the knee and shoulder joints, where the angle of joint movement is relatively large, should be cautious to use this Xian Cao Bone Pain Patch similar to the hot compress treatment. Once the joint temperature is too high, it will lead to exudation in the joint. Once the inflammation exudes too much, the exudate will not be absorbed and the joint will be obviously swollen, which will affect the joint activities at first and later induce joint adhesions and joint stiffness, leading to a state of joint dysfunction. Therefore, if the symptoms of joint pain appear, try not to use Xian Cao Bone Pain Patch.
