I was thinking of the amount of pain that could be caused by having to pull an attached tick from the inside of your nose. Maybe I just have a ridiculously sensitive nasal interior.
This also reminded me of a story told at another camp about a woman who fell asleep sunbathing. A few days later she developed a persistent itch in her cheek. Doctors were unable to find anything and assumed it was psychosomatic. The itching got worse and she was hospitalized and put in a straitjacket to avoid harming herself. Then she managed to get free and ripped out a large chunk of her cheek which was full of ant eggs.
It seems funny now. It kept me up nights at the time.
