lately i've been coughing really badly, and it's starting to hurt when i cough. it feels worse than a cold...when i sneeze (which i occasionally do, as with every normal person) it kills my throat! i'm young, so i don't smoke or drink, but i don't know what to do. my mom just thinks i've got a cold, but i KNOW it's more than that.

also, today, as gross as it sounds, i almost choked on my own mucus or whatever was in my throat. i was in class and i ran outside without saying anything and coughed really loudly, trying to clear my throat. my friend told the teacher that i could breathe and everything so then my teacher sent me to get water. but i'm scared.... please help
