Actually, I Have A Lot Of Back Pain,due To A

Actually, i have a lot of back pain,due to a stress fracture in my teens. This came from sports, which I played all thru college and then was a professional fighter for 7 yrs. So the beating on my body is extensive. I really tried the holistic approach along w anything but meds. But I'm only getting older w a family to support. Methadone has been the best and longest lasting med I've ever used. But it seems almost impossible to get a prescription from any doctor. Why is this??
