Wherever you are sitting, really slump forwards. Get a really horrible scrunched up posture – and then breathe in. That’s how I am. Not slumped, but that’s as much as I can breathe in most of the time. Over the last few weeks I’ve had this effect come and go. I was being good with my inhalers anyway but they weren’t helping. Not a full asthma attack but it feels like the start of one.
Then toward and over the weekend it got worse. Saturday got really close to me wanting / needing to go to casualty and felt very odd when at one point I broke out in a sweat all over. But then it calmed down a bit. So one breath in several dozen is okay, the rest not. Pulse is okay. It’s very odd and may well not be asthma but whatever it is the worry level isn’t going down. And you probably have no idea how tiring breathing actually is.
