I have a very itchy rash on my chest for a day and now (within 12 hours) it is going up around my neck. It is very very itchy and irritating. I am not taking any meds...at all and I have not used any different detergent or creams. The only thing that I have done recently is put Johsons baby oil all over my body after a shower, but there is no reaction any where else. The rash is spreading over chest and neck!!
