What?!?!

That seems to be the word of my day today.. About a week and a half ago, I started having issues with my ear. It has that plugged feeling. Well, I went to the walk in, and they thought it was because my sinuses were draining. They gave me medication. I took it, its gone, and my ear is none better. In fact, its really bad.. and my hearing is awful. I cant hear any of my students today. They have to be looking right at me, and i have to be within a 3 foot area of them in order to hear. Its getting really irritating. Plus, its the bad thing where you can hear yourself really loud, but nothing else. Thats getting old too. I just want it back to the way it was... Goodness.. Thats all Im asking for...I want my ears to feel normal, and i want to be able to hear..
