Dr. Rowe shows how to quickly relieve erector spinae muscle tightness and pain. The erector spinae are a muscle group that run the full length of the back, directly off to the side of the spine. When they get strained and inflamed, they may cause pain and aches throughout the whole back. What usually causes this is tightness and weakness in the erector spinae.
