I get periods of being very out of breath, wheezing etc. currently in the midst of one, lasts a few days to a week usually. I've been to the Gp a few times over the years and initially it was put down to b12 deficiency (now under control) then iron deficiency (now under control). I don't (as far as I know) have asthma. I'm not currently ill with anything that I know of, just very out of breath. Baffled!
In case it might be relevant, I ALWAYS get crackly breathing sounds when I lie down whether I'm currently breathless or not. Again have mentioned it to the GP, they didn't think it was anything.
Anyone any ideas?
