I did not find the test for coronavirus to be at all unpleasant, painful, scary, or invasive. The doctor told me to take my mask off and stuck a q-tip up my nose. He didn't poke my brain out with a stick and it didn't make me gag or bleed or pass out. It made my nose tickle a very little bit and my eyes tear...but not enough to even notice.
If you are supposed to get the test but are afraid of it, please don't be. It literally takes seconds and could save you or someone you love a lot of trouble, and getting a negative result will give you peace of mind.
