What is a trigger point?

 

A trigger point is a tight ropey band of muscle, also called a “knot”. Trigger points can be caused by direct muscle injuries, secondary to spine conditions such as a herniated disc or repetitive microtrauma. Microtrauma is developed from lack of exercises, prolonged poor posture, vitamin deficiencies, sleep disturbances and joint problems. Trigger points cause pain and spasm in the muscles. When not treated the pain causes spasm and the spasm causes more pain.

 

What is a Trigger Point Injection (TPI)?

 

Trigger Point injection's have been shown to be one of the most effective treatment modalities to inactivate a trigger point and provide prompt relief of symptoms. The basis for a trigger point injection is to relax the area of intense muscle spasm. By relaxing the muscle spasm, blood flow to the area is improved thus, allowing the washout of irritating metabolites. Injections are done in the office and usually take 15-30 minutes to administer. A small needle is inserted into the trigger point and lidocaine or marcaine is injected. While the needle releases the trigger point the lidocaine/marcaine numbs the area for post-injection pain control. The injections may cause a twitch or pain that lasts a few seconds to a few minutes. Several sites maybe injected in one visit. Prolonged relief is usually achieved with a series of injections.
