I had a high ANA count..
Winter 2005/6 they said it was 1:160 which is in the high range of lupus.. three weeks later I tested again and it was back down again

, I think at times we get false negative tests because of the effects of RSD on our immune systems I was all swelly achy too at the time so my inflamitory system (everywhere) was whacked at the time as it would be for lupus too.
I sure hope you get a diagnosis soon.. we hope it's not RSD but best to know right.
hope this helps ease the mind a bit on lupus.. it's a nasty too.
