For some patients experiencing pain, trigger point injections (TPI) may be an option. When appropriate, TPI is a procedure used at Team Health Care Clinic to treat painful areas of muscle that contain trigger points, or knots of muscle that form when muscles do not relax. In many cases the knots of muscle are so pronounced they can be felt under the skin. Pain is caused when trigger points irritate the nerves around them.
What is involved in a trigger point injection?
In the TPI procedure, one of the Team Health Care providers will insert a small needle into the patient’s trigger point. The injection contains a local anesthetic or saline, and may include a drug called a corticosteroid. The injection renders the trigger point inactive and the pain is usually alleviated. In most cases a brief course of treatment results in sustained relief. In some cases, several sites may be injected in one visit.
Trigger point injections are used in many applications
TPI is used to treat many different muscle groups. These muscle groups can be located in the arms, legs, lower back and neck.
