I have been getting red large bite like hives on my arms about every 2 weeks. They are very itchy and go away within a few days but not I have a rash on the top of my nose that looks like a burn with blisters that are swelled up and have yellow crust. It us painful and also have swollen lymph nodes. I am on antibiotic from the clinic but the Dr Didn t say if was an infection. He said maybe it was or maybe from the sun... Not sure if the marks on my arms have anything to do with my nose
