If the rash came right after you started the med I would ask him. As far as Lupus rashes, they can be anywhere and there are so many different kinds. No two cases of Lupus are the same. I would talk to your doctor about getting on plaquenil, which is the main drug for Lupus. It takes a long time to start working but it really does help most of us
Lupus flares are difficult to deal with. There are a few threads in here now titled something like "how do I make them understand" or sometime close. Read them. There are some wonderful stories in there that may help your friends and family understand what you are going through.
