Please help me understand the Parazapper!!!

Can someone please tell me how to use the copper paddles from the parazapper to treat specific areas?

I'm trying to zap two specific areas; my uterus and my left shoulder. If I put the paddle/lead with the positive charge on my stomach (red line), am I supposed to hold the paddle with the ground or negative charge (green line) in my other hand away from my body? Or am I not supposed to not touch the negative paddle when I'm treating a certain spot? Should I just sit it away from my body?

Please help! I don't want to make my problems worse!
