Trigger Point Injection
A trigger point is a painful area in a muscle. It may feel like there is “knot” in the muscle or an area of tightness. When pressure is applied to the trigger point, the pain spreads out to other areas of the body.
A trigger point injection is a shot that is given in this painful spot.
