ok i'v had this problem for more then 5 years now. My nose is always clogged up--- that means summer winter spring it doesn't happen only in spring. Because of that i always spit because i feel like i have something on the back of my throat and this isn't only saliva it's salty and when i'm sick it turns brownish or yellowish. Also when i spit i have the feeling i'm gonna vomit which sometimes happens.So what could this be??????????
P.S I'm a 18 year old boy
Also i saw a doctor he told me it was dust allergies but the medicine didn't do sh?t
