^ I am no doctor, I would hope you are seeing a good one, but I've had back pain every since I twisted my back playing football in sixth grade. I finally went to one of the best back doc's in so cal as an adult and he showed me a bunch of exercises to do that stretch the back and neck muscles that really help me a lot.

You can probably find them on webmd or something but basically you get down on all fours and arch your body up as far as you can (kinda like a cat ) and then slowly arch the opposite direction, and and then twist right and left. I do this all the time in the morning and it really helps me but, like I said, I hope you are seeing a real doc about it in case its something more serious. good luck.
