Unexplained pain in the index finger

According to the TCM meridian theory, a person's five-finger fingertips each have meridian points, and they are closely related to the internal organs. If one fingertip is particularly painful, it indicates that the internal organs associated with this meridian point have a certain problem. Forefinger pain: There is a Shangyang acupoint associated with the large intestine on the forefinger. If there is constipation and the finger is deeply painful, there may be a problem in the large intestine.
