The literature that I have read about
Erbitux indicates that the rash normally gets better after the first couple of weeks. I'm sure that the antibiotics are helping also.
The Aquaphor was a product that my radiation nurse gave me to use on my radiation burns at first. I got some relief from it until the last 3 weeks when I got no relief from anything. Are you sure that they said to put it on the rash? I agree with you that it seems like the opposite of what you would want to put on it. The Biafine is wonderful and really helped to heal my burns quickly. I was quite a bit better about 2 weeks after my treatments ended.
Glad to here that H is doing better and I hope that it is all finished soon.
