I too had a lingering cough from bronchitis for months. Eventually, We thought it was maybe reflux related, but turns out it was due to the blood pressure meds my Dr put me on. All of a sudden one day, I remembered her telling me that 10% of people develop a cough. Once I started another BP medication, the cough stopped. Are you on BP meds?
