Definition:

Lidocaine is a local anesthetic, which means that it causes temporary numbness when applied to a part of the body. Lidocaine is often used in trigger-point injections to alleviate pain in a specific area. It can also be given intravenously for treating widespread pain.

In fibromyalgia, some early research suggested that intravenous lidocaine may be effective against fibromyalgia pain. However, later research found no positive effects.

Trigger-point injections using lidocaine are a common treatment for myofascial pain syndrome, which frequently overlaps with fibromyalgia.
