Anybody had an extended dry, "fake' cough with a chest vibration?

My daughter gets one every year lasts 2 months she goes to an allergist for it. It is caused from dust particles in the air. It's just a dry cough she doesn't even know she's doing it after a while they give her an antihistamine nasal spray. The doctors didn't know what it was and tried all kinds of crap so we took her the allergist and he caught it right away.
