Tramadol
"I have a pinched nerve in my pelvis and for about a month I couldn't sit on the couch or a stool or even lay down in bed without severe pain in my lower back and even into my leg. My doctor put me on the tramadol and for the first time in over a month I was able to sleep with no pain. My only complaint is that it makes me feel incredibly itchy, I got great sleep, but I do remember rubbing and itching my face all night."
