DH has had a cough for ages, he mainly gets it when exercising but coughs other times too. It was really bad but easing off, but when he goes for a run he has to stop and cough up phlegm. He went to docs twice - once he was told to take a certain cough medicine - that's nearly all gone now - and this time he has told him to see the asthma nurse. He says he doesn't get a tight chest, just the cough and green/yellow phlegm. Does asthma sound likely? He is getting fit for the RAF so asthma would be devastating to say the least. :(
