How to ease this uncomfortable pain?

It feels like the soft tissue inbetween the back of my mouth and nose is very irritated. I feel nauesous too. I can breathe through my nose, and my head doesn't feel congested but my ears might be a bit. My throat is sore if I yawn. Its just REALLY annoying and stratchy and sore and my dad has it too. I noticed it this morning. Last night I couldn't sleep worth anything, I fell asleep late and work up early tossing and turning just like how I fell asleep. It almost feels like I never actually slept but I can't be sure. So I'm thinking a restless night might have made me susceptible to something. How do I ease this? I tried showering and drinking hot/warm water.
