K.S.
Hi A. -
My infant son also had a rash on his face. My pediatrician just kept telling me to use hydrocortisone, but it would work for a few days and then come back. Other lotions didn't work either.
I finally took him to a regular dermatologist here in Oswego who right away diagnosed him with having eczema and wrote me a prescription. It was way better within a day or two and now only flares up off and on and once I start him up on the medicine again, it goes away.
(As an aside, he had been sleeping really badly and waking often, seeming just miserable, and as soon as he started on the medicine he slept through the night! I guess it had been itching him, poor guy.)
I know that Oswego isn't near Glen Ellyn, but the dermatologist that I took him to is Dr. Anna Vawter at the Oswego Dreyer Clinic. I would think that just a normal dermatologist would be able to help you.
I hope I was able to help.
K.
