Steve has lots of coughing episodes (not just when eating and drinking). There is white phlem and he takes ages getting it up. He has had this cough for the last 7 months and seems to be getting worse. he has had a chest x ray and this shows no problems and the community matron says as long as the phlem is white there is nothing to worry about - but I do!! Has anyone experienced anything like this? Any help and advice would be appreciated as its spoiling sleep as well as being very disruptive during the day and tiring him.
