I was doing squats, with the total weight of 135. After I did one squat, I had super sharp in my lower back, and can barely bend down to touch my toes. After two weeks, the pain subside but when I sit for 45 minutes or more I have a pain that originate from my right lower back and go down to my right leg. I have tried taking muscle relaxers and pain med. in addition I've been doing stretches and foam rolling, but I still have pain in my lower back when bending to get something off the floor and the pain that would go down to my right leg. Please help me find what's wrong with my back/ back muscle. I really want to lift weights again.
