I'm also in a pain management program I have severe nerve damage in my back due to a accident I have been in the program for over 10 years. I take oxycodone but recently I tested positive for hydrocodone something I have not taken for many year if you have any information for me I would be very grateful.

It sometimes happens that hydrocodone, actually the metabolite hydromorphone will show up as a result of taking oxycodone. What type of test was this and where performed?
