Hello. I have Lupus and Sjogren's and got a large 2nd degree burn on my lower back from my heating pad that I use constantly for my low back pain due to arthritis and herniated discs. I can't find any information on the internet about how my diseases may affect my burn, its healing, and infection. I'm on Plaquenil, Methotrexate, and prednisone. It's been 5 days and it's not getting any better. I know healing will take longer, but I don't know what to expect. I've been following all the advice about wound treatment, but I'm worried about infection and how everything else will come into play. Does anyone have any advice that has had a similar situation? I live in the U.S. and don't have any health insurance at the moment because my husband recently lost his job or else I would have already gone to the doctor. I don't even know what kind of doctor I would need to see with all I have going on. Any advice would be gratefully appreciated.
