Middle finger pain of unknown reason

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. Middle finger pain: There is a middle acupuncture point on the middle finger, which is located on the pericardial meridian that surrounds the heart. When the heart cannot stand due to the heat, it will feel pain here.
