The ENT I saw didn’t find anything more than slightly more mucous than expected and suggested I see a speech therapist for the nagging cough and hoarse voice! Cardiology discovered asthma and pulmonary led me to gastroenterology. Mine worsens following a meal , snack, heck anything I eat triggers increased phlegm and congestion and hoarseness. lol no I’m not a cardiologist. I’ve just been under cardiac care since 2002 when I had a viral induced cardiomyopathy diagnosed.
