I was at work today and at the register, my right hand, wrist and forehard started to to twitch uncontrollably and violently. After that my whole body starts to shake pretty hard, enough for a person to notice and I was trying to count back this guys change and it was really hard to concentrate. I notice that my entire right arm was feeling weak and uncoordinated. I had gotten sharp head pains on top of my head a little to the right off and on that day. Then that happens! I wanted to run out of there but I just went to the bathroom from a few minutes. I thought I had a mild seizer or something. I felt weird and still feel weird as I am typing this. Also had some breathing problems, like I couldn't take a breath.

Any of ever have this happen to you?
