Welcome to the boards.
In response to your question about rashes I get 3 diffrent types. I get this wierd thing where I will feel an itchy tingly spot on my arm or wherever and I will look and there is a small red bump, almost like a pimple, a few minutes later it dissapears. The second kind of rash I get I will get on my shoulders, arms, and back, this is a series of small clear blisters in a clump, they also itch but they take a week or 2 to go away. Finally, I have my "perma rash" (or so I call it because it doesn't go away) on my cheeks and nose, this is just a smooth red slightly raised area that does not burn or itch. I thought it might be the "butterfly rash" you would find in lupus but it does cover the folds of my nose. Needless to say I am an itchy, rashy, person. As far as the lupus testing goes, from what I understand the ANA blood test is a pretty common test for lupus. There is a sticky-post on the lupus board for blood test results, baybe you should go check it out. Hope this helps!
