Hi,
My mom had the Erbitux rash--her skin was painful to touch, it looked like onion skin, and oozed--she stuck to her sheets, pj's, etc. Her Chemo doc gave her a precription for minicyclene (Sorry, can't recall the spelling) and we used Aquaphor all the time. Once we had the script/aquaphor combo things calmed down within days. She does have a slight scar where the skin peeled...I call it her medal of honor!
