An excessive leak of ACh causes localized muscle fibers to stay in a state of permanent contraction. Clinical diagnosis relies primarily on manual palpation by

These sustained contractions compress local capillaries, leading to ischemia (reduced blood flow) and hypoxia (low oxygen). These sustained contractions compress local capillaries

The resulting "energy crisis" triggers the release of inflammatory substances like bradykinin, serotonin, and substance P. These chemicals sensitize local pain receptors, creating the characteristic "exquisite tenderness" and referred pain. 2. Identifying the "Knot"
