I have somewhat of a sore throat , but it is not in my throat it is more at the entrance level before the uvula . It is not a constant pain, but when it starts to hurt it s like a quick stinging-like pain, and then it also hurts briefly to open my mouth to a certain extent. Also, when the brief pain starts, my neck feels tender. Then it goes away and may repeat in a few minutes or in the next hour. What could this possibly be symptoms of?
