Can Rashes With Drainage From Ears Be Indicative Of Impetigo?

My 20 month old daughter has a crusty rash with drainage from her right ear. Tender to touch but no pain otherwise and no fever. The rash extends to smaller round bumps on her face but is clearing up there. It looks very similar to impetigo but it has a very strong odor and I have never heard of an odor associated with impetigo. Her pedi is on vacation and can't see her until Friday. It started last Friday and I am worried a week is too ling to wait. Does it sound concerning?
