I have severe lower right back pain it hurts when I lay flat and try to stand up straight. And when I lay down and move my legs it hurt too. I also?

Back spasms? may have strained back ? lift something? in jury ? if urine symptoms may have kidney stone? drink lots of fluids, take excedrin or aleve and tylenol. use biofreeze gel and ice pack or heat pad whichever works, rest 2 days , if not better see a dr. be sure not constipated.
