5 yr old has severely itchy toes with no rash

[HurricaneFrances]

My 5 yr old has been complaining of itchy toes, both feet, just the tips.  For the past week, she cries the itch is so severe.  There are no visible signs of Athlete's feet, rash, sores, cracking, but she hates wearing socks so I am thinking it could be fungal vs allergies.  She has no known allergies to foods, environment or medications. Benadryl has not even been helping.  She has always been mildly itchy to wearing socks or itchy clothes but never has she cried so much over an itch.  Coincidently she got the H1N1 Flumist last week the day the itching peaked to this level. She did not spike a fever, just developed sinus congestion and bloody mucus in the nose. She has never has any reaction to previous vaccines and it may be purely coincidental.
Does anyone have a child with itchy feet who refuses to wear socks?

Hi, my daughter has the same symptoms and she didn't get the vaccine. So I am writing this to hopefully set your mind at ease. I don't know what the problem is, if you find out please let me know. :)
