What is happening with me?

I have been sick for 3 days now, on the first day I was sick, I had a severe sore throat, a fever and constant shivering. I didn't feel like getting up at all because of mild nausea. The second day the symptoms were the same. Today, my fever has gone away, I feel better to walk around now, but I have a sore throat and a few new symptoms. For some reason, about a couple hours ago, I have had CONSTANT salivation in my mouth, It is like putting a sweet candy in your mouth. I am having pain underneath my chin where these 2 muscles are (I am not sure why they are) but I believe it is from the insane salivation flow coming for my mouth. About 10 minutes ago, another symptom occurs. My ear starts to feel clogged with liquid similar to having water in your ear from swimming. It is in my right ear, and it feels painful. There is a difference In hearing from my right ear to left. The right war feels harder to hear from. Can anyone tell me what is happening?
