My Brother has had a cough for 7 years non-stop. He has never smoked, is mot a drinker and he is in fairly good health for his age of 74. It breaks my heart to hear him cough and I cant imagine what it does to him. He lived abroad and saw many specialists and had many tests. He was told there was fluid coming from his lungs which they think is causing the cough. A lot of mucous is brought up when he coughs.
He is now living back in the UK, has seen a specialist and has to have some procedure in September.
No doctor or specialist has gotten to the bottom of this yet.
If anyone has been successful in finding a cure please let me know.
