Trigger Point Injections (TPI)


In the TPI procedure, a small needle is inserted into the patient's trigger point. The injection contains Lidocaine, a local anesthetic (numbing medication), and it works by blocking nerve signals in your body. With the injection, the trigger point is made inactive and the pain is alleviated. Usually, a brief course of treatment will result in sustained relief.

TPI is used to treat many muscle groups, especially those in the arms, legs, lower back, and neck. In addition, TPI can be used to treat fibromyalgia and tension headaches. The technique is also used to alleviate myofascial pain syndrome (chronic pain involving tissue that surrounds muscle).
