Trigger point injections are performed to relieve knotted muscles called trigger points. In the TPI procedure, a small needle is inserted into the patient's problem area. The injection contains a local anesthetic, saline, and an anti-inflammatory medication. With the injection, the trigger point is made inactive and pain is alleviated. Usually, a brief course of treatment will result in sustained relief. Injections usually take just a few minutes, and several sites may be injected in one visit. If a patient has an allergy to a certain drug, a dry-needle technique (involving no medications) can be used.
