My best guess is Roseola - he has had cold symptoms for over 2 weeks now and a med-high fever for the past 5 days (103 for 2-3 days). His fever hasn't broken completely though, it was 100 today. He's been on antibiotics for an ear infection since last Monday. The rash showed up suddenly yesterday afternoon but has gotten worse today. It's a raised rash, but it doesn't seem to bother him (like chicken pox or hives would...although he's scratched at it a bit when he doesn't have a shirt on). Any other details you need? Help me out here, moms, what do you think?
