My Boyfriend's mother was diagnosed with lupus this past weekend after she was admitted to the hospital with a bad case of hives. I was under the impression that it took a long time to diagnosis someone with lupus, that there would be blood tests etc... but they have not ran many tests on her at all, the only thing she is complaining about is when she gets hot she get hives all over her body. I am not familar with this disease and I was wondering if that was a common symptom, no where online have I found where it said it was. She has been under a lot of stress lately and I was under the impression that she just had a case of hives due to stress.

I am also wondering if anyone knows of anything I can do to be supportive, I am not really good with things like this and I really don't know what to say to my boyfriend to make him feel better about the whole situation. Thank you for any advice or information you can give me
