I totally understand! I wish I could give you a big hug. I frequently go numb in various parts of my body, but I've been blessed that it usually goes away after a few hours. A few weeks back, while I was at school, I went numb from the shoulders down. They wheeled me out of class in an office chair, down a hallway full of people. I was mortified. My dad had to come in and half carry me out to the car.
