Hello, I have numbness in my left heel, which started about three days ago. I am not diabetic, and did not injure my foot, also I do not have a arch, just in cause that matters. I don t recall stepping on anything or being bit by an insect. Actually, the numbness first started in the tip of my big toe about 2 weeks ago, but that has subsided, now the numbness is in my heel. When I walk on it, there is the dull feeling as if it was a blister on the bottom of my foot, but there is no swelling. I pocked that area with a sharp object just to see if there is feeling, and it is, but it s dull. What could that be and what should I do, short of going to my own Dr. Thank you in advance.
