What is BOTOX?


BOTOX is a neurotoxin medication used to treat contracted muscles that can cause pain. At CHANGEpain, BOTOX is used to treat chronic migraines/headaches and other contracted muscles.

How does it work?

BOTOX is injected into contracted muscles, causing them to temporarily weaken and help them relax. BOTOX is believed to also work by altering pain signals from muscles to the brain.

A solution containing BOTOX is injected at specific skin or muscle points. The number of injections during a treatment session depends on the pain area. For example, the PREEMPT migraine/headache protocol involves 31 injection sites, whereas treatment for a single contracted muscle might only need 3 injection sites.
