What a comfort to read all these comments. I have suffered with this for a little over 2 years. My primary care doctor said "it's sinus drainage" and prescribed nasal spray. That didn't work. My gastroenterologist said "it's reflux" and prescribed medication for morning and nighttime. Even performed an endoscopy and only found very mild evidence of reflux. None of the medications worked. I finally went to an ENT who sent me to voice therapy. I went for 5 weeks learning various breathing techniques to calm the cough. I had high hopes this would work, but unfortunately it did not. The next step was a laryngeal block. It helped for about a day. Then it seemed like my cough came back with a vengeance. I had an ENT appointment this morning. She prescribed 10mg of amitriptyline with the potential of increasing the dosage as needed. Again, I am super hopeful this is the answer. This cough is so bothersome. I just want it to stop.
