hi, sorry to hear about yopur partners pain. You may already have your answers, your message was posted long ago.
I ahve spent 15 years inadequately medicated, and 5 years properly medicated.
Personally, I found that the lyrica was more efficient than the oxycodone and oxynorm. However, having weaned myself off the oxy' moderate release, I use the oxynorm 5mg up to 5 times per day, when needed, and increased the lyrica up to 300mg. Iam currently on 600 mg of lyrica, use oxynorm only in a crisis, and have jjjust been prescribed a new drug, still an opiate, but not quite as mind bending as oxynorm. Will try to find the packaging and email/contact you again. Unfortunately the pills are downstairs and i am stuck upstairs. hope this is of some help and wish you both well as you can be. regards Gemma
