Seriously though,
>>12691696 is pretty spot on. They stick a swab up your nose just a bit further than feels right but it's over very quickly. I've had it done four times (all negative!) and individual doctors/nurses will have slightly different techniques with rubbing the insides of your nasal passages. Most rub up and down but one nurse did a twirl in my nose and it felt weird for the rest of the day.
