I recently woke up and could hardly move, I was in so much lower right back pain. I have memory problems, am 76 and a widow living alone. What did I do to myself? I just woke up (it is 1am) and am having pain again and have to move very slowly - bending over is a killer! I am going to take some vitamin C, and oxycodone, if I can find any around the house. I am 76, a widow and live alone! Should I go to an emergency room for analysis/diagnosis?
