Trigger Point Injections
Trigger points are focal regions of spasm and inflammation in skeletal muscle.
Trigger points may occur in the upper spinal region resulting in neck pain, shoulder pain, and migraines. They may also occur in the low back or less commonly in the extremities.
Typically there is a palpable nodule or tender point in the muscle where the trigger point is located. The area is sensitive, and often when pushed, pain spreads out from the trigger point itself to a region surrounding the trigger point. Trigger points often accompany chronic musculoskeletal disorders like fibromyalgia, myofascial pain syndrome, neck pain, and lower back pain. Acute trauma or recurring minor injury (weight lifting/sports) can result in the development of trigger points.
Typically local anesthetic and corticosteroid is injected.
