I've noticed over the last couple of months that I'm getting increasingly breathless when walking around, without necessarily feeling wheezy. I don't necessarily feel my chest getting tight- I just feel as though I can't get enough air, and I often have to stop and catch my breath.
I mentioned this to my new GP, who lent me an oximeter to see if this showed anything. While sitting still, my sats are usually 97%, but the moment I start moving they drop, anything down to 88% or so. Once I sit still again, they very quickly come back up again, so I'm not worried, just a bit confused. Strangely the degree of drop doesn't seem to correlate with how breathless I feel - sometimes 92% feels worse than an 88%.
Does everybody drop saturations when they move, even those without asthma? Is it that my asthma is not as controlled as it should be, or is that I am simply unfit and need to try and do more exercise? My pulse also goes up to well over 100 when I start moving, so is that a sign that I'm unfit?
Unfit or asthma? Or normal?!
