@cmb1 ... Sorry to hear that you have difficulty coughing up mucous without causing pain in your head and eyes. I have found that lying down for postural drainage with my head cushioned helps. There are also head bands for headache sufferes that might give you some relief, but changing position and supporting head all around if necessary would be my first suggestion. I found that zinc supplement helps with GERD treatment to decrease the airway sensitivity. Be good to yourself and find some comfort.
