Active trigger point release: technique, after-effects and precautions

A physiotherapist first checks whether the tender spot and movement pattern fit a muscular source. The clinician then applies tolerable pressure while you shorten, lengthen or move the involved muscle in a controlled way. The aim is to reduce local sensitivity and make movement easier, not to crush a supposed knot. Trigger points can coexist with joint, nerve or tendon problems, so the response to pressure alone does not establish a diagnosis.

Tell the therapist about recent injuries, blood-thinning medicine, easy bruising, altered sensation, skin problems and any symptoms that travel down an arm or leg. Pressure should feel manageable and should not create sharp, electric or escalating pain. After treatment, follow the movement or strengthening plan given for the underlying problem rather than repeatedly pressing the area. Gentle activity may be more useful than guarding the muscle completely.

Stop the technique if it causes numbness, tingling, marked weakness, dizziness, severe pain or rapidly increasing swelling. Seek urgent care after trauma when there is deformity, loss of limb function, a cold or pale limb, or loss of bladder or bowel control with back pain. Fever, unexplained redness and warmth, chest pain or breathlessness should be medically assessed rather than treated as a muscle trigger point.

Ask what examination findings suggest a muscular contributor, which movement should improve, and how many sessions will be tried before reconsidering the approach. Request a clear home plan that avoids pressure over nerves, blood vessels, the front or side of the neck, broken skin and recently injured tissue. Discuss other options if relief is brief or the technique is difficult to tolerate.
