Well, we started off the day at Prompt Care because Boo had a rash when he woke up. He was pretty cranky all evening yesterday. That's so not like him. He's such a happy guy most of the time. He's been on an antibiotic since Wednesday for his ear and sinus infection. Sooo...my guess was an allergic reaction to the antibiotic. Soooo...we went to prompt care since it's the weekend and his usual doctor is unavailable. The doctor there said it definitely looked like an allergic reaction and gave us a script for a different antibiotic. No more zithromax for us I guess!
