Trigger point injections are intended to treat pain that radiates from a trigger point to a sensitive area in the muscle or connective tissue (fascia). Trigger points are painful “knots” in your muscles. They form when a muscle can’t relax. Sometimes you can feel these knots when you rub your muscle.
Trigger point injections inject a small amount of anesthetic and steroid into the trigger point to alleviate the pain. Trigger Point injections are also used to treat conditions such as myofascial pain syndrome or other chronic pain. After a trigger point injection, you can actively use your muscle. However, you should avoid strenuous activity for the first few days.
