I have had chronic throat clearing for several months. larynoscopy, endoscopy, barium swallow all negative. nexium, (esomeprazole) nasacort didn't help. any ideas?

Cough: Are you taking any medications that could cause a cough - stopping these may help. Trial of a medication to help reduce the cough, tessalon perles, (benzonatate) may be a benefit. Also, testing and treatment of asthma may also help reverse the symptoms.

Habit: Since it developed over the last few months my first thought would be a post nasal drip possibly caused by allergies. However, if the nasacort (triamcinolone) has not helped and tests have ruled out the other possiblities, it may just be a habit that you developed.
