Nutramigen not enough???

My son has been on Prevacid solutabs 15mg per day for over two weeks now and Nutramigen for over a week. The reflux symptoms seem better but he now has a rash on one side of his face again? Could this be a milk allergy? I would say his stomach is better on Nutramigen but not great.

He is not napping unless held and he wakes frequently at night and will not go back to sleep after 4am. (I do have the mattress elevated) I am just at a loss because the pedi did not test him for a milk allergy but they said he does have the symptoms for an allergy.

I guess my question is: what are they symptoms of milk allergy, and should I try an elemental formula such as neocate?

Thanks for your responses
