12 y/o Daughter has sudden rash

My daughter developed a sudden rash on her arm a few months ago. It consists of four or five roundish spots about 1-1.5" in diameter. They are slightly raised, light on the inside, darker on the outside and grainy. Sometimes they become more pronounced ~ I don't know what the trigger is. After a few weeks, she developed a rash around her mouth (looks like sever chapped lips) and her cheeks (reddish spots, bumpy). We took her to the doctor and she got a cortisone shot, which seems to alleviate the symptoms to a degree (the spots on her arm never went away). A month later, the rash is back. She now also has reddness around her eyes which she says it painful (it looks like dry, taut skin). I thought at first it was an allergic reaction to something (we tried avoiding milk and sugar, that didn't seem to matter). At this point, I'm at a loss ~ the rash on her face looks almost like perioral dermatitis, but the rash on her arm does not. Does anyone have any ideas I can check into? Thanks in advance for your help.

Put this up on the Doctor Dermatologist sitem you may get better input, Have you been to your own Doctor to get it looked at? What does she do with her arms does she wear any jewellry there or a long sleeve sweater bought recently has she used new Skin cream shower Gel or anything she could be allergic to.How about her diet any new food or drink any new glass or cup shes drinking from.Go to your search engine and put Rashes in it comes up with all kinds of Rashes .you can put in what it looks like .

Thanks for your response. I will be taking her to an allergist, since the general consensus is that this is an allergic reaction. It's upsetting because it was so sudden ~ one day she's fine and the next day she's not.

It looks to me that if you bend the arm at the crease the circles almost meet.  any new lotions being used or bath soap or anything like that?
