question: My 15 yr old daughter starting complaining of a sore throat on Thursday. It is still bothering her. She started a fever about 24 hours ago. She is having diaherra and not eating very much. She is drinking a lot of water to stay hydrated. She is unable to talk. I was just thinking it was a virus, but now I wonder if she has strep throat. None of my children have had it in the past. How long should I wait to take her to the doctor to possibly get tested?
