rash on face...misdiagnosed as baby acne?

My baby has a horrible rash on her face that tends to get worse when she is awake(crying, eating, being held). It started out as a bunch of red bumps and is now very dry looking with some yellow crusty areas. It's on her checks, chin, neck, upper back and chest. We took her to the doctor Thursday and it was diagnosed as neonatal acne but that was before the dryness and yellowness appeared. What could it be and how do I treat it? Should I take her back to the doctor?

Hello,
   since I am not a pediatrician or dermatologist, I can not provide any other ideas about diagnosis. I would give your doctor a call and update him/her on the situation. If you feel that the baby is showing any worrisome symptoms you have been told to look for (such as an elevated temperature) then call the on-call physician at your practice or take the baby to the emergency room.

Best Wishes

Definitely take her to the Dr. It may be some type of allergic reaction. Was she inroduced to anything new since this started?
