I experience the same things with post nasal drip. It does create a nasty annoying cough. That is usually a sinus infection. Or allergies. You, may want to ask a doctor if he can prescribe you some nasal spray like: Nasonex, Flonase. They help. I take Nasonex daily and that really helps that sinus drainage and such sorts. Thats my suggestion to you elder power. Good luck with that. Bye.
