I feel for you! I was up a lot of the night with the zingers also. Didn't get on the boards though since the computer was upstairs and I was downstairs. Ice helped me a little bit with them, didn't take them away completely though. If anyone has any other ideas, I'd love to hear them!
Zingers are these jolts that feel like you're being electrocuted. They zap you in the end of your foot like a lightening bolt and happen out of the blue. I believe it's the nerve trying to heal, or something - who knows. They come and go. Mine were gone for quite a few weeks and then yesterday appeared again. I know they'll calm down. Exercise helps a little, but I believe that's what brings them on too.. or just being uptight and nervous, who knows. They're not fun, I do know that.
