question: My 5 yr old son has pitichia on his cheeks.  The only medical problems I am aware of are his seasonal allergies and mild asthma.  Could the pitichia be caused from rubbing his eyes?  He is in the 95th percentile for ht.  And the 90th for wt.  His wt. has never been a concern of our pediatrician.  He has a muscular build.
