"this medication helped me survive until they found the real problem with my back, which took about a year and several progressively invasive procedures. i can say in my experience that after surgery i continued having pain but once i weened off and my own endorphins kicked in i actually felt much better. even my pharmacist said there have been cases of the medicine actually causing pain and i experienced it. i will say in my experience there is a difference in generic medications vs name brand and even differences in different manufacturers.
