Yes. He has chronic pain. He broke his neck and back and the nerves for his arm got ripped out of his spinal cord. Docs and he says it feels like its on fire all the time, as if his arm fell asleep (pins and needles) but 10 times worse. I know he's going take something for the rest of his life. He abuses his medicine, he doesn't take it the way he should (he crushes it). He goes through it faster then he should and has to go through withdrawal till he sees the doctor again. Tell your friend to be careful with this drug. It's addicting and you get amuned to it so you have to take more and more in order for the pain to go away. I don't know if my husband needs it for his pain or his addiction. I've never taken the stuff and I do not allow him to keep it in the house (I have three children ones a tween and 2 are toddlers). I hate it and I hate his doctor for giving it to him.
