How to Do a Trigger Point Injection Into Trapezius Muscle

The trapezius muscles are a pair of adjacent muscles extending from the middle back to the top of the neck. If someone you know experiences chronic back or neck pain in her trapezius muscles, her physician may recommend trigger point injections. You can administer this type of injection designed to relax knots of muscle and relieve pain. This therapy also treats headaches and fibromyalgia.
