Good morning, Glad you posted Theresa!
Generally I'd say keep looking for a rheumy that you feel comfortable with, but in this case I think the most recent one you've seen may be on the right track. Without knowing what is going on (everything changes with Prednisone), she is being smart not to give you anything. While you may want to get on another rheumy's schedule, keep the appt with this Dr and see how the 2ond appointment goes. If it goes well, you can then cancel the Dr you haven't seen yet.
It certainly does sound like something is going on, and I wouldn't be surprised to find that it's autoimmune of some sort.
Hang in there,
