Anyone here with children with severe milk allergies had issues with
chronic dark undereye circles?  My daughter frequently has this,
especially from about mid-October to April, and I used to wonder if it was
a mild reaction to a cross-contaminated food but now I wonder if it is an
additional, possibly environmental allergy.  However she has no other
chronic symptoms.  Last year she had a cough that lasted several weeks
coinciding with the dark undereyes but this year the cough cleared up much
more quickly (and without any medication).
