Excessive Acetylcholine (Ach) release seems to be related Calcitonin Gene-Related Peptide (CGRP) inducing Ach leakage. CGRP is part of a general inflammatory response, in turn part of the pain response associated with trigger points.
Physiologically spoken, acetylcholine (Ach) is released in the neuromuscular junction by the ...
Increased vascular permeability means fluid leaks more readily from blood vessels. That leakage builds up in the surrounding tissue, which causes edema. The edema squeezes veins, thereby compressing them, which means they can't do their job of draining the tissue efficiently, and that can lead to the vicious circle he mentions.
Vasodilation means the ...
