I think morphine is probably the best pain killer there is but most doctors won't prescribe it uness you're terminally ill. When I had a herniated disc I tryed Hydrocodone but it had zero effect on the pain. I'd be very carefull about doubling up on any pain medication. A good friend of mine lost his 25 year old son because he had over medicated. He had severly injured his back and was taking pain medication (I don't remember what). The pain was unbearable so he kept taking more and more trying to get some relief. He took so much pain medication that he went into a coma and died 2 days later.
