Trigger Point injections are performed to treat painful knots or bands of muscle known as “trigger point”. The doctor will press on the trigger point(s) to identify the painful areas and using a small needle will inject medication to inactivate the trigger point. A local anesthetic is typically injected. In addition to temporarily numbing the area, the injection is intended to inactivate trigger point by disrupting muscle fiber activity and/or nerve conduction. In some cases a steroid (long-acting cortisone type medication) may also be used to reduce pain associated with inflammation.
