@hosford42@techhub.social Then yeah, I would definitely strongly recommend seeing a doctor if that is an option available to you (they will likely also do an oxygen saturation test, as pretty much the first thing).

Given that I'm not a doctor, there's probably not much more I can contribute here, sorry :( Besides the standard advice of "take rest, don't force yourself to 'work through it'", that is...

I do hope you will find a speedy recovery!
