Well this has never happened to me before. And it recently just started this week. And i dont think is a common cold. I have alot of Mucus in my throat, i try and swallow and it doesnt go down. Also i try and clear my throat and it doesn't go awayIt has also made me throw up once. My nose is stuffed and i feel like i constantly have to blow it. And since my nose is stuffed i have to breath out of my mouth, but the mucus in the back of my throat that wont go away, is making it hard for me to breath. I'm pretty sur ei have no allergys to anything either. I am guessing it could be post nasal drip but i am unsure. can someone help me out?
