Hi, @arlinebringhurst - just a thought, since I've also dealt with chronic cough and went through a lot of testing for reflux, sinus issues, allergy, asthma, etc., plus various medications. What finally seems to have helped me is taking mometasone and formoterol (Dulera). It may have also helped me to move from a 70-year-old home to a 20-year-old one.
