Hi, my daughter was just at the doctor as was told she has pharyngitis. her strep test came back negative. They gave her a magic mountwash prescription to pick up at the store. Symptons that started Monday were: sore throat (which has slowly gotten worse over time). her tongue is a bit swollen as well as her throat. she has white spots on her tonsils and she has a huge number of canker sores on the back of her bottom lip - all different sizes but the inside of her lip is covered with them. She hasn t eaten anything unusual. She has been swimming in the Willamette River with friends, but that is the only thing I can think of out of the norm. no current boyfriend. any ideas? thanks
