Sounds like you where very conservative with the pain management? (maybe that is a good thing?), I never tried "Oxycodone" but I hear that they can be quite addictive, did you switch to some other weaker painkiller? Just be careful not to jump back into training on the same level as before...
Take it easy!
I’ve used one ibuprofen but definitely want to avoid those opiates unless you’re in serious pain. Not only addictive but you can build a tolerance to them too.
