Back pain!

My back is KILLING ME. It hurts so bad. I even called my doctor because I was in so much pain. I think it's just normal aches and pains but it's so severe that I can't get comfortable at all, no matter what I do. It's frustrating. Anyone have any advice on how to manage this? I've taken Tylenol but it doesn't help as much as I wish it would and I also don't want to take it too frequently.
