@lilymol Gosh, a couple of months? That’s too long when you’re feeling awful! Are there any medical centers within 1-3 hours away? Or a university medical center? I ended up going to a university med center about 1 hour away. I got great care there.
Since you have autoimmune diseases already, I suggest that can call the rheumatologist who treats you. Can you do that?

@lilymol i found this doctor that might be of help. She may, at least, be able to give you some names of doctors in your area.

Can you try calling her tomorrow?

I find the advice on GERD triggers on webmd to be very helpful. I drink hot tea (chamomile) after meals. I like some applesauce with my meal, seems to help also. Some of your meds, like prednisone, can cause constipation. Your Dr could give you Ducolax, Senna, daily metamucil or other remedy to help you with that. Also, taking a daily walk and drinking plenty of water, eating soluable fiber can help.

@lilymol You have your doctor and he set up some appointments for tests for you. Have you had these tests before? I do know that someone will need to take you to both tests and then drive you home after. Be sure to discuss with that person what your symptoms have been and what you want to know. You’d like them with you whenever the doctor is explaining things. Two ears are better tan one!!
Does someone usually accompany you to doctor appointment?
