I’m fit and healthy but have had a cough for more than a year, what’s causing it? DR MARTIN SCURR replies

Dr Martin Scurr replies: What a frustrating problem. A chronic cough – one that lasts more than eight weeks – is common in those over 60, particularly in women. Dr Martin Scurr replies: What a frustrating problem.
