The nose knows.

A Cornell University Student decided to study where is the most painful place to be stung by a bee. The result: the most painful place to be stung by a bee is the nose, followed by the lips. To come to this conclusion, Michael Smith had honeybees sting him 190 times on different parts of his body, including his penis, testicles, armpit and cheek. – Time Magazine, 4/7/14
