It seems like there are many of us with this mysterious chronic cough/throat clearing condition. Have had it for decades, originally thought it a bout of bronchitis. And then it continued. Saw multiple ENTs, GI docs, allergists, a pulmonologist, speech therapist. They call it multifactorial and so I take PPI, allergy meds, none of which address the issues. I wish I had answers for all of you for this (thank goodness) not serious but nonetheless quality of life issue. It would be interesting as a group to find out if we have any common denominators, i.e. medications, illnesses, that might make things clearer. Anyway good luck to all.
