Hi, i just need abit of reasurance, i've had a flu virus the past 3 weeks which turned into a sinus infection, then i went abroad for a week and it was very hot!. Now i'm bk home i've been back to the doctors as i'm coughing alot and constantly wanna clear my throat and chest, but nuthings shifting.... The nurse said i have ( post nasel drip ) , i've never had this before, i've been having a beconase spray and doing the bowl of steam but its not easing up, my mouth, throat and nose now feels bone dry, i'm still coughing, my chest is tight.... Why isn't it clearing it?!... Thanks :)
