“left bum check is very sore just to touch, it feels like it is on fire and when I feel it with my hand it feels like it is bruised, my left big toe is numb also got some pain in left calf and on the bottom of left foot get a electric shock numb kind of feeling” are indications of nerve irritation or injury.
