Didn't develop any as far as I'm aware. Existing ones may have gotten worse but I have yet to actually go and see as they're not bothering me (one is the one I get blood tests for which hasn't bothered me ever aside from the mild inconvenience of having to travel half an hour to a major hospital for the blood tests, and then they finally decided to transfer care to my local doctor which is right there and even has a pathology unit in the same building but local doctor never got back to me about that, the other is lung issues that developed about a decade or so ago when I had a chest infection and shingles at the same time, which apparently meant chest infections every winter forever after).
And also couldn't go see the regular doctor about the lung issue anyway as covidiocy meant that they either weren't "allowed" or weren't allowing (from the way the receptionists were talking sounded like the former) any and all respiratory issues (which was irking the staff as they know exactly what my problem is and know it's not contagious).
Well that sucks!! I have a colleague who gets sinus infections every autumn - not fun. Guessing chest is worse.
Covid stupidity continues. People have made it part of their identity now.
No biggie, it's only a problem if you like breathing.
That makes a few things make sense.
