Causes of trigger point problems

Trigger points are actually the result of the interaction of calcium and adenosine triphosphate (ATP) on muscles that have been stressed in some way. This causes a sort of contraction that shortens the muscle in a localized area, producing a taut band. This in turn generates a lot of localized and uncontrolled metabolic activity in the area, and a decrease in blood circulation, which releases substances that make the nerve endings hyperirritable – and the result is pain. In some cases, microfilaments in the muscles can occur, as well as scar tissue and adhesions.
