Trigger Point Injection for Back Muscle Spasms
Description of Trigger Point Injection
A back muscle spasm is an extremely common cause of acute and chronic neck pain and back pain. Spasms often present as painful “knots” within the muscles. The muscles of the neck and back can be so uncomfortable that they also restrict range of motion. In addition to physical therapy, trigger point injections are also used to help reduce the inflammation and irritation within the muscle.
