Does anyone else still get breathless on exertion. I walk every day (2 young dogs) through sand dunes so reasonably fit, average weight. If however I take on a massive sand dune for example I seem to get excessively/worryingly breathless. I know our anaemia is megablastic but my doctor won't have it that the breathlessness and PA are linked. I have had spirometry test and lung function is great.
Anyone have anything to share and maybe shed some light
