Hello, I have this pain in my neck when I swallow. Its close to the back of my tongue, and now every time I swallow it feels like I am swallowing mucus. I started getting this pain a day after I ate a bag of hot chips that I usually eat once in a while and really never get pains at all. I have tried gargling salt water as well. What is this? And how do I cure it? If it goes away by its self, how long does that take? I am a Male, Age 17
