Ewwww!
I clean my earlobe out, use rubbing alcohol on it, and occasionally put Neosporin on it when I wear an earing, to keep infections at bay.
Speaking of Ewww! I over-stretched an ear piercing once and it became more and more painful. Then a huge throbbing blood blister formed behind my earlobe. When it finally burst, I was buying a dvd at HMV. Blood was dripping on to my shoulder like a faucet. The clerk almost fainted or hurled, it was hard to tell. It was most embarrassing but at least the pain was gone.
