Hi, Our daughter is 21 and has been suffering from the following symptoms: extreme sore throat, swollen glands at the back of throat, so large they are felt against back teeth, severe mouth sores - which are prohibiting eating , and a fever that has been as high as 101 but stays around 99 degrees. She has had these symptoms for five days - she has been to urgent care twice - first diagnosed with a bacterial infection and the next day with a viral infection.
