It's been noticeable for six months that I have been breathing heavier.
And in the last week, I've found it harder to catch my breath.
I run three times per week for 30 minutes each time.
I walk my dogs every day for an hour.
I am active and reasonably fit. But I am perplexed. What could it be?
I'm making an appointment at the doctor but I'm really worried.
I'm 49. Used to smoke heavily but stopped 17 years ago. Could I have developed COPD or even lung cancer?
