PMR: Please suggest important first questions to ask rheumatologist

I was diagnosed 3 months ago by my GP after 2 months of pain. I am on 15 mg prednisone which initially took most of my pain away. Now I find everything creeping back but still not nearly as bad as it was. Fatigue is really crazy as well as hand and foot cramping. I do not know what is prednisone… what is because I am trying to do to much, I just am very afraid of pain returning full on. I want to make this first meeting as informative and productive as possible . What are some important questions that I may not have thought about but should be asking? Thank you !
