I am a master's degree nurse practitioner.  I see that a lot of people ask questions on this site that they should be asking their health care providers.  Whether they are medical doctors, nurse practitioners, dietitians, or others, you are paying a lot of money for their services.  Each of you are such unique individuals, that it would be unwise for anyone to give specific medical advice.  Yes, please share coping mechanisms, emotional support, and the like.  But corner your provider until you get an answer that makes sense to you.  If you have a provider that won't explain things to you, then it's time to move on.  Do not be afraid of these people!!
