I had this cough about 3 weeks now and i tried everything for it to go away. But it wont go away. My chest is even wheezing. Should i be worried? I dont smoke and im 21yrs old! Im thinking if this cough isnt gone bye first of the year then im going to the er. Im so sick and tired of thks cough and sometimes i have a hard time breathing and all i have is an inhaler. Its so annoying. I just want it gone asap!
