What is a Trigger Point?
A trigger point is an area where tension levels are high in a specific grouping of muscles, and it triggers pain in another part of the body, unrelated to the trigger point. For example, a trigger point in the lower pack may trigger a pain response in the arm.
A trigger point is commonly caused by an injury, repetitive action, or poor posture. Over time, the muscles tighten and pull together. The area may feel tense or knotted, and aside from pain, you may also experience limited mobility.
