Hi, I've been trying to get in shape and have been working out for a few weeks with out any problems. But last week I spent the night at a friends house and when I came home the net morning, my lower back was really sore. My mom and I thought it was just because I fell asleep sittng up on my friends couch but It's been really hurting all week. I've been using a heating pad and I've tried stretching, butit really hurts. It especially hurts when I bend down, sit down, or stand up. I was wondering what I could do to releve the pain?
