Do you by chance have a puffer on hand in case you need it? Ventolin type puffer?
Make sure you call doctor or go to hospital if you get worse. Very serious.


On all accounts here in Australia at least I've noticed , if it's Omicron, and you've had your vaccinations, you probally won't get it really badly. (EDIT - as long as you don't have other serious health issues that is)

I also wonder if the back ache you've been having was part of this.
