"i have taken many things for my pain. i have had a level 3 spinal fusion and need more back surgery. my doctor gave me opana and kept me on my oxycodone for break through pain. what a huge relief and not only that but the opana did not give me that high feeling and i&#039;m able to get around like a human again. i have to say the opana gave me at least 8 hrs of relief and i was able to sleep and get up the next morning and move, where as before i woke up so stiff, sore and could hardly move."
