I do flexing exercises at times such as moving the toes both upward toward and then away from the shin area. Lately I have noticed when I move (at the ankle) my left foot upward toward the shin a sensation almost like something is lightly tearing within my heel. Now there is a numb area in my left heel and it appears to be spreading upward in the back of my heel. I'm 65, fairly active, in good health and take no medications. Could I have torn something and is it possible to heal by itself? This numbness in my left heel only affects about two inches in from the back of the heel and seems to be spreading upward along the back of my heel.
I've never noticed anything such as this and any information would be greatly appreaciated.
