I have had a cough for 11 years. It started with symptom similar to asthma attack, I could not take a good breath for 2 hours. I Have had this about 7 times in 11 years...then it is gone, I mean totally disappears and I am fine. I have this chronic cough that is harsh. Sometimes I cough up phlem, but not always. I have seen an allergy/ asthma specialist, had the allergy stick tests, all were negative. I have been on many inhailers, they only seem to make me cough more. Most nights I only get 2 hours of sleep at a time. I have had 2 open heart surgeries, 2016 for valve replacement, then a year later 2017, to repair torn interior sutures ( probably from my violent coughing) I am fatigued ALL the time ant have shortness of breath and wheezing. Now I just found out my Thoracic Aorta has enlarged to 4.8. Any thoughts to my cough?
