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&#039;s not to say that I don&#039;t have bad days, but compared to all the other meds I&#039;ve been prescribed, Opana definitely ranks #1. It took a few weeks for me to feel a positive effect, but I&#039;m glad I suck with it. It&#039;s the best."
