If not Oxycodone then what pain reliever/ feel good pill should I use?

Instead of trying to find a pill, why not try things like warm baths or mages, or even going to a chiropractor! The thing with pills is that you "come down" from the high and actually feel worse. Then, you need more and more, etc......see what I mean? If it's chronic back pain, perhaps a mild muscle relaxer would help, but only when needed. Unfortunately, there aren't any "magic" pills out there like you want without risk of addiction......or worse. I wish you well.
