I got hit by a car while on a bike and the only thing that was hit was my left leg . At the time my leg looked like the muscle next to my shin had been dented but i could still walk on it with no problem . Now my leg has no pain , however a small patch near the shin feels numb and devoid of muscle.
Nothing needs to be done for this. Just do regular tolerable exercises, walking,and jogging, the muscle will strengthen in few days
