Glad to hear your update and that you got treated...it just sounded WAY to much like Strep. Unfortunately, those "rapid strep tests" are fals negative way too often...and if someone is presenting the way you say you were, I can't imagine not treating them with antibiotics while waiting for an actual culture to come back from a "send away" lab.
Hope you are feeling better soon!
P.S. Watch the kiddos...this can be really contagious, and the little ones might only present with low fevers, going off their food or drinks, and some get nausea and vomit. Take them to the peds asap if you think they might be infected, even if it's mild symptoms and tell the peds that you were diagnosed and treated recently.
