I generally don't seem to have any symptoms apart from shortness of breath, except when I do a lot of exercise.

I can exercise intensely up to my lower lung ceiling, but what's far worse is the next day if I exercised for a long period, even if not intense.

I played 18 holes of golf yesterday and this morning I felt like I'd been hit by a ton of bricks. I've been here before but this was as bad as ever. It seems as though more than the lung shortcomings are a great incapacity to do considerable labour without paying a huge cost later. It was THE one thing that changed more than anything.
