Just be careful. I'm in a minimal risk bracket and usually get over stuff considerably quicker than most and it is still a vicious ride. I keep picking things up I would normally just not even notice and nothing happens! Fatigue and weakness last a long time apparently as well.
Welcome to my world. That describes me for about a week or more after a proper asthma attack. You feel basically OK, perhaps a bit rough around the edges, but the second you try and do something, like walk more than 10 feet, or pick something up, you realise that you're buggered. Haven't had to contend with a proper attack for a long time (crosses fingers, touches wood).
People tend to treat asthma as something relatively mild and don't realise how debilitating it can be - one day you're tooling around on a bicycle overtaking people half your age and generally being surprisingly fit for an old git and the next you'd lose a fight with a kitten. An ambulance paramedic I used to know socially described an asthma attack, just from observing patients, as "like trying to run a marathon while breathing through a drinking straw", he was pretty close. The upside is that if getting this is only as bad as a proper full-on asthma attack then subjectively I'll cruise through it, if and when I get it, because my perceptions of a 'bad respiratory day' are on a different scale to most other people's.
Speaking from experience, don't overdo it, don't even
try to do it. Sit back and do nothing, the less you do the sooner you'll recover. The less stress you put on all the 'get oxygen to where it's needed' apparatus the sooner it can recover; and understand that normal everyday activities count as stressors at the moment. Get the little house slaves to do all the work (as long as that won't give you food poisoning).
