The agonist point is a medical term used in Western medicine to describe acute or chronic soft tissue pain, and refers to the presence of a very small point in the muscle tissue that can trigger pain in the entire muscle. The point of agonism can be very small in the early stages, but as the local muscle is gradually damaged excessively, exertion can lead to the gradual enlargement of the point of agonism, which is actually a very limited muscle spasm, or muscle contracture in the muscle tissue. When this muscle contracture is stimulated by excessive pressure, or pulling stimulation, there will be an explosion of widespread pain, or even localized numbness, as well as the phenomenon of spasm of the entire muscle, and there may also be localized muscle stiffness. In fact, the painful point can be interpreted as the abnormal state of the local muscle tissue produced by external stimulation.
