No I've not tried that but in reality, I'm not experiencing any sort of rash like symptoms. The skin and "surrounding area" are perfectly fine - there's no rash or redness but the burning sensation exists....that's what's making it hard (at least for me) to figure out what to put on it or if it's completely related to my output. I will say that it is at it's worst (worse?) when my stole is loose or almost all watery or loose.
