Bed bugs, MAYBE???

Ariel woke up Saturday morning at the hotel with these bites on her. She thought there was a mosqito in the room and I thought they looked like flea bites. Needless to say, they were itching like crazy.
Treated her with itch cream and Benadryl on the way home and by Sunday, still no better.
I treated her with a gel I used for poison ivy, cause I knew it would dry them up (or it did my poison ivy) and help with the itching.
She had these on ONLY her feet and hands. Anyway, my self treatment must have done the trick, b/c by Monday after she came in from school, they are looking better.
Needless to say, it still creeps me out as to WHAT it was!
