You've been waiting 7 months to see a rheumy??? Good grief! I wish you'd been treated earlier, as it's no fun to have your mobility compromised. Or maybe I'm reading that incorrectly. I hope you have a good Rheumy who is remicade-aware. I know there are issues with remicade & Lupus, but I don't know much more than that they exist.
Here is a somewhat older thread from our Crohn's Forum where you can read some discussion about
it.
www.healingwell.com/community/default.aspx?f=17&m=1145863 I see there is another med some people have been able to move to that doesn't create the Lupus issues.
Best wishes, let us know how it goes.
