Sucks to be me right now.

For the past 3 1/2 hours, I have been itching all over my body. No signs of a rash. I didn't use anything different. I haven't taken or eaten anything different. Benadryl hasn't done anything to help. I'm about to lose my mind - distractions aren't working well either. I'm tired, frustrated and ITCHY!

UPDATE: The itching went on for about 2 days and then just stopped rather abruptly. Still don't know what caused it or cured it.
