Right on, well OC should help with all sorts of pain, how much do you take, what's it for, and what's your opiate history?
I don't know your medical situation but if it's some type of neuropathic pain you're dealing with, might be other medicines that work on it. Don't quote me on it but I think tramadol, cymbalta, lyrica? have been used for that. Amongst others.
But I figure if you can't get it done with OCs or morphine, I would probably give kratom or o-dsmt a shot, opana next.
It's all about dosages and your body. I don't have much schooling, but can tell you that you probably want to avoid fentanyl and such as much as possible.
Certainly would also just be better practice to consult someone that is booklearned and licensed before you start diving through a laundry list of opiates to figure out which one is stronger than oxycodone.
