I pulled my back. what do i do?

Any red flags?: Back injury is a very common condition for which xrays, ct scans & mris are useless unless you have certain red flags like high speed motor vehicle collision, gun shot wound, weakness, incontinence, fever, injectable drug use, etc. Most back pain resolves in a few weeks.
