Hello, for the past few days I've had a rash on my chest. It didn't really itch, but it got bigger and bigger. I put some cream on it thinking its eczema, but I believe it could be caused by the peanut allergy. It started itching yesterday. It's been 24 hours since I last ate peanut butter and when I last ate it my rash spread to under my chin. I have no idea how to get rid of it, and the more I itch it the more painful it gets. This is the only symptom I have had and it's really irritating me. I put some moisturizing cream on, which makes it go away overnight, but the catch is I get really itchy still and when I itch it it gets worse. Please help, I don't know what to do!  ( this photo is the mild rash )
