First I want to welcome you to your new family. I am a relatively new member here and I feel like this is my extended family.
I hope that you can find a new rheumy, that will listen to you and will do what it takes to get you help with your problems. It is very possible that you have both, RA and lupus. I have both, plus fibro and I am going to be checked for raynauds, scleroderma and sjrogrens. I am looking for a new rheumy as well, because mine is in such a hurry to get me out, he is dismissing my complaints, saying " that is normal with lupus, or that's lupus for you." I understand, that we don't have enough specialists and that they are very busy, but when I finally get in to see him ( after waiting for 3 months), I want to be able to talk to him and he should listen to me and help me.
Good luck to you.
