Andrew111, Cookey is right, you should not have to suggest medication to the doctors but definitely let them know you are in pain and what is, and is not working. Usually they start with the mildest of pain medication and then step it up to stronger ones as needed. Pain control is a team effort, your job to let them know you are in pain, doctor's job to do something about it. I would hope you have ready access by telephone or at your appointments to let your needs be known. Do not be shy about asking for what you need, treatment is hard enough without enduring discomfort that is avoidable. Side effects of narcotic analgesia are drowsiness which usually subsides in a couple of days as your body adjusts, nausea and constipation. Anti-nausea medication and laxatives should be taken routinely when using narcotics to prevent those side effects. If you are on tube feeding you could also ask dietician for a formula with extra fibre, also keep well hydrated.
