Hey Candybear,
Don't be so hard on yourself. After working in an ER for years, I've seen plenty! SI'ing in there doesn't even make the list.

I do hope you'll be careful however. You don't want to cause permanent damage or get a nasty infection. Perhaps you'd consider putting an ice cube in there? It would be painful, but not leave cuts and/or scars.
Take good care,
Okie
