Anyone know someone with Lupus? I'm thinking Erin might actually have that too. She has a skin rash on her arms and it gets worse in the sun, she has heart pain, sensitivity to light big time, swollen lymph nodes... her doctor pointed out that her last visit but I didn't put it all together until now. :C hopefully not, but should get her in. I don't know much about Lupus. How bad is this disease?
