Questions about a Charlie Horse?

Last night I had a Charlie Horse. It was unbelievably painful. Afterward I could barely walk because the muscles hurt so bad. I thought it was weird because I got it in both calves at the same time. Has anyone ever had it in both legs at the same time? Also, for abut 2 hours afterward my legs still hurt (not like the pain of the Charlie Horse, more like sore after a workout) and my whole legs were shaking.
