Ready for a little bit of TMI?

I was sitting here, and all of the sudden I get an electric shock like feeling down, ahem, below. Felt like I had to go pee, but at the same time I was getting the shock there, I also felt the same shock on the bottom of my left foot. Happened about 3 or 4 times, so I figured I better go to the bathroom and relieve myself
What the heck? Is that a nerve crosswire, or what?
