There are many causes of chronic intermittent cough. One common one is acid coming up the food pipe (GORD) and another common one that's often missed and not addressed is chronic post-nasal drip. You should speak to your healthcare provider. Have you tried some daily antihistamines with a nasal inhaled steroid? Often your doctor might empirically try antacids. Please discuss this with your healthcare provider and take it from there.
