for a week I have had severe pain in my left leg. it keeps from sleeping or when I do sleep it wakes me up. It is located midway down my calf to to the outside side of my leg . It feels like is under the muscle next to the bone. At times it seems to migrate. It moves to my left foot at the top of my arch or it moves to the outside of my left knee.
