I m an 11 year old girl, 3 days ago my throught was dry, next day sore, and today even worse. I can barely eat or drink anything without pain, not even water or tea. And every like 30 seconds of so when I have to swallow my spit, I can barely do that. I looked and there are red bumps in my throught, not too big, but not too small. I ve already tried gargleing salt water, what else can I do, and what do you think I have?
