Jolting shock down forearms during push-ups?

I just decided to do some push ups, and on about my 10th rep I got this intense 'electric shock' down both of my forearms and I dropped. There is now a slight numbness in my forearms. My left forearm now feels like I got a charlie horse, and my right forearm feels like I was sleeping on it (knuckle side where the shock happened). Any ideas?
