A muscle relaxer like cyclobenzaprine allowed me to sleep. It may be your Quadratus Lumborum (QL) mm. This website has a good explanation of what happened to me after I bailed while riding a longboard and hurt my back.



Has some good rehab stuff for after the acute pain phase is over in a few days, I had 3 days of being bent over, pain that took my breath away, and couldn’t get comfortable, but it does get better!
