I have been experiencing postoperative pain since getting a back injury operation in late 08. I initially just take regular painkillers but since they’ve become worse, I’m thinking of using a stronger med like ultram. My friend who has fibromyalgia uses it and so far, according to him, it’s worked wonders for the pain. Before I go ahead and ask my doc about it, do you know of any bad effects this med might cause my body if I go ahead and try it out? Thanks for the help!
