Is there a good strong pain killer that doesn't harm kidneys/heart/liver, i only have one kidney pain is from degeneration of discs, neck &spine?

Most R OK: The nsaids r the meds 2 avoid. All narcotics r ok if you r @ that stage. Get 2 a pain clinic 4 evaluation, a reputable one!

Careful: Most of the narcotics have Acetaminophen in them. You want to limit yourself to 3 grams of Acetaminophen a day, otherwise it can harm your liver. Roxicodone has no tylenol (acetaminophen) or Ibuprofen in it, however.
