help!!!

Anyone know anything about skin rashes? I have one that went from little red spots to large blotches with red outer rings and red/purple/gray centers in about 5 days. I'll hopefully get into a dr mon/tues but won't know for sure until at least tomorrow when I call for an appointment.

I posted pics on twitter @jeslowe115

At first I thought it was a reaction to laundry detergent or a medicine but I changed detergent 2 weeks ago (back to the old stuff) and stopped taking the medicine in question 5 days ago. And it's only getting worse!
