1. Axial low back pain isn't a proper diagnosis, it's a symptom.
2. First step is to rule out red flags then likely time, rest the area, OTC meds, and maybe PT.
3. Next step is to get a proper diagnosis. Treatment depends on what this is.
Incidence of knee causalgia skyrocketed in the last several yrs, and it didn't take another Civil War with bayonets and muzzleloaders. THANK GOD for DRG bros...
