I had one like that- I grabbed the nurse's arm to stop her from going all the way in and she still tried to press on, saying these tests need to go deep, bullshit. instant runny nose and pain for days- same as the other 2 times in my life I was "tested for flu" - never again. I only did it to assist a family member in the hospital. In order to stay I had to submit to the test. they sent security to remove me if I didn't do it.
