Allergic reaction?

We have had some type of illness in this house for what seems like FOREVER! One kid gets healthy and someone else picks up the slack and catches a new yucky virus. We had Adeline with an ear infection Monday 2/11. D'Angelo ear infection 2/13. Days following, everyone gets cough, congestion and irritable! Fevers. Yesterday Rick and I took all 5 to the doctor together.
How many people can you fit in one exam room? We had the seven of us, the doctor, a med student to assist and our double stroller. I think we win-LOL. The conclusion was something viral. Great, good times, let's wait this out. My favorite part of our visit was while 4 out of our 5 were crying/screaming the doc looked at the med student and sighed, "Ahhhh, the joys of becoming a pediatrician". I laughed.

This morning when I went to get Adeline from her bed I found her looking like this. I called the doctor and the nurse thinks it is an allergic reaction to the antibiotics she took for the past 9 days. Benedryl has helped with her facial swelling, but she still has the rash all over her entire body. Two doses down so far. If it hasn't cleared by tomorrow I am taking her in to be seen again.
