I know most of you are not doctors, but some of you are bound to have had this ailment before. It started with minor lower back pain Wednesday night, but has progressively gotten worse until now. I can't lay down, I can't stand up and I can only sit on my left buttcheek. Walking is a major ordeal. Luckily, I had enough hydrocodone from a previous injury to last me thru the weekend. I have tried heat, cold, stretching, etc, with no relief. The pain goes from my right lower back all the way to my ankle, and my foot is cold, numb and tingling. Besides the ER, what can I do?
