question: I have several back and neck problems. i have been taking oxycodone for years and had one surgery so far and may be looking at another soon. the oxycodone 10 I am currently taking is not working any more, My sister takes roxicodone 15 that help her considerably but my pain doctor says they are really bad for you. Is there that much difference in the two. I know none are good but I don't have any chose anymore.
