I have had asthma since childhood (now 45) and a productive cough for 6 years. This summer I had a chest infection which I had trouble getting rid of followed by some issues with fungus in my sputum (which seems to have gone now as last sputum gets was clear). Currently waiting for appointment at the hospital initially with general medicine but will hopefully be referred to a chest specialist (I live in Shetland so you have to be seen by general medicine first before you get referred to a specialist in Aberdeen). Hopefully then I’ll find out what is causing the cough, asthma or something else. In the meantime X-ray was normal and I’ve just had spirometry. Everything was normal on my spirometry apart from my FEF25/%75% which was low (sorry don’t know the actual numbers). In fact my lung volume and peak flow were better than normal. The person who did my spirometry said that this could indicate and issue with my small airways. But I’ve no idea if this is an asthma issue or something else. Has anyone else had similar results (normal spirometry but with low FEF25%/75%)?
