For the last week I have been getting a electric shock feeling from my left elbow to my left shoulder. The first time it happened it was a weak shock feeling that happened 3 time in a five minute period. It didn't really hurt I just thought it was odd. Since then it has happened a hand full of time and each time it has been worse. It happened last night and it lasted a few seconds and was very painful. This morning the right side of my neck hurts so bad I can't look to the right without turning my whole body and I can't move my right shoulder without pain.
