My Bronchiectasis has improved and my lung specialist has told me my lungs are good but I don't understand why I still get breathless when walking up an incline, or doing chores. (he doesn't have an answer) I accept that I am very mild so why does this happen, specialist seems to think it's because I don't do enough exercise. I walk as often as I can up to 2 klms usually with rests. Could the problem be that I'm 78 and slowing down.
