I have dear friend who is an internist. He has told me that for many chronic illnesses there are protocols that are proven successful in a large majority of patients. He said his personal frustrations happen when people refuse or are afraid and then do not follow through on other suggestions. He never forces anyone to take any drugs because that is the patients right. But he has told me it is difficult when the condition worsens because it may well have been helped. He also prescribes pain pills sparingly, but will not let anyone suffer needlessly.
