I just got off the phone with my co-worker. Her 2 kids have something similar to what Ben is going through. They've had it for 12 days now and it's showing no signs of letting up. Her little boy has had really bad hives too that haven't responsed to Benadryl at all and hasn't eaten anything but a slice of cheese in a week. She now thinks she's getting it too. Maybe it really is just a uber nasty virus.
