Muscle Referral Pain and Trigger Point Therapy.
When muscles are injured and a nerve is pinched, the muscles that the nerve(s) runs through will develop Trigger Points in response to the pain and will send a pain signal where there isn't necessarily an injury, causing referred pain. For example, if you have pain in lthe lower back, the muscles in your buttocks will be to tight, causing it to press on the nerve sending a message of pain to the back.
Trigger Point Therapy releases the point of pain and not the referral pain area by applying pressure directly at the site of the Trigger Point for a short period of time. This breaks up the muscle fibers within the adhesion and releases the toxins that have built up. Once the muscle fibers are broken up, they begin to repair and eventually they return to their natural state, ultimately releasing the muscle memory associated with the injury and healing the pain.
