YYYY@YYYY My husband has been diagnosed with IPF and is currently suffering through coughing attacks that he believes are related to PND. He has tried the over the counter allergy meds on advice from his pulmonary doctors but nothing seems to help. He has finally agreed to see a physician but I am not sure whether to schedule with an allergist or an EENT. He recently has suffered from dizzy spells and/or blurred vision that lasts only a few minutes when he turns his head and then turns back quickly which I thought could be related to his inner ear. He does not complain of pressure in his ears or sinuses. Do you have any suggestions about the medication for PND or to help his coughing subside? He constantly uses cough suppressants. Thank you for any advice you have.
