What is a trigger point? A trigger point is a hyperirritable spot that is painful.

A trigger point is a hyperirritable spot that is painful. It is called a trigger point because it "triggers" a painful response. But a trigger point is more than a tender nodule. It affects not only the muscle where the trigger point is located, but also causes "referred pain" in tissues supplied by nerves.

Trigger points are located in a taut band of muscles fibers. The trigger point is the most tender point in the band. The therapist will locate and deactivate them using “Dry needling”.
