What do I do?

My 3 month old has eczema so when he had a little flare up I tried soaking him in aveeno oatmeal bath and as soon as I took him out this red rash started forming all over his body and keeps getting worse. His doctors office is closed and there isn’t a 24/7 line to call so I can’t ask hi Is it an allergic reaction? What do I do? :(
