"i have tried many different medications for my back, i have deteriorating arthritis in my lower back along with curvature of the spine. i am currently on opana er 10 mg twice a day, and norco 4 times a day for break through pain. when i get up in the morning i can hardly move, i take the opana and within half an hour i can move better. i still have pain but not as intense as it was. it has helped a lot. i would not be able to afford this medicine without the coupon."
