I hope those tests come back negative, that's a lot to deal with! I was convinced I had RA because I've had terrible joint pain since I was a kid, and two of my family members have it. My doctor ruled that and lupus out in the process of diagnosing me, and says that the joint pain can be a symptom of MS. I hope that's true, because my knees and ankles and hip bones hurt almost constantly.

I have no advice, but you'll be in my thoughts. It sounds like you've been through more than enough medical yuckiness. I hope the joint pain goes away; hopefully it's an MS thing that will ease over time? I'll be hoping for the best.
