pain
"Opana is the Most effective of all the opiates I have taken for my osteoarthritis. What used to make my life a living hell is now under control. That's not to say that I don't have bad days, but compared to all the other meds I've been prescribed, Opana definitely ranks #1. It took a few weeks for me to feel a positive effect, but I'm glad I suck with it. It's the best."
