Hello, Friday evening around 4:00pm (3 days ago), I had a vibration feeling between my legs while I was driving. At first I thought it was my cell phone but it was in my purse. Very weird feeling. I was been getting it off and on since then. It only last but a second and goes away. A couple minutes later, I get it again. Friday evening, when I went to bed, I couldn t sleep because it kept happening. What could this be? Thank you for your time, Bambi J.
