I've had one Covid test, nostrils only, back in March for a surgery. I wasn't looking forward to it, given all the reports of "it feels like they touch your brain."I have to say with all the complaints I've heard from family getting tested, I was expecting something worse than we had. A quick swab around the mouth, and then the inside of the fleshy party of each nostril. The swabs needed for operations are much worse than what's being done in Australia.
It wasn't anything like that. One nostril was absolutely fine, and the other one burned a little, like when you some water or something like that in it.
