I am experiencing this sharp, sudden pain almost like electric shock type of pain on my right lower leg. It only happens like within a second but it happens so fast and severe, it makes me twitch every time like really, I got electric ran my leg. It doesn t feel like it s muscle, it s more like nerves. It runs from a little above the ancle to mid calf (outside) There is no sign before hand, it just happens. What is this?
