"i have lupus, arthritis and had most of my back crushed in a auto accident. opana is the only pain medication that has relieved a majority of my pain throughout the day. i take 40mg every 8 hours and i am able to walk around and do things i couldn&#039;t do before when i was on the patches and all the other drugs i tried. opana is the best long term medication that keeps working without fail for me."
