We waited. We went through lots of Tylenol. On Friday morning his fever was down to 99.5. That's the lowest it was all week without any medicine. By Friday night his temperature was normal. He was eating dinner.
Then the phone rang during dinner. It was a nurse at the pediatrician's office. She was calling to say that the lab results showed that my 5 year old did have strep throat. She wanted to call in a prescription to the pharmacy. She was surprised when I said that wasn't necessary. Actually it was necessary 5 days ago! But by the time she called he was feeling much better.
I understand that sometimes those instant tests can give false negatives. But if they suspect a false negative do they have to wait that long??
Today my 5 year old is feeling like his usual self. He's back to fighting with his older brother.
Now I'm holding my breath and hoping that no one gets sick for Thanksgiving :S
