Hi, Your mother should not have to suffer pain. I am a nurse and the wife of a cancer patient. First as a nurse I was always taught that if the patient states he has pain then they have pain. My husand's doctor and Nurses could not do enough for him in the way of pain management. They gave him whatever he needed and they let him be the judge of how much that should be. No one in pain should have to suffer. Please take your mom to another doctor. LM
