Hi, I am 26 and had to have my tonsils out at the age of 17.    
I had a low grade fever for 2 years (aka the problem started when I was 15) before I had them out! I would suggest having her take some time off school to stay home and recoup so she can heal enough to have them out. I know it is a pain, but for me surgery actually cured it and putting it off and taking antibiotics for long periods of time caused some issues that I still have today.   
When you are sick for a long period of time, you start to get depressed and forget what it is like to be well.    
I opted to try everything else for two years before I finally decided to have them out. Unfortuantely, that had me on multiple type of antibiotics for long periods of time. Those can cause a "yeast imbalance" (if you know what I mean)--I still have issues with yeast til this day.     |
