Think about the difference between your skin and the rubber soles of your shoes. You can walk on hot surfaces or sharp rocks without feeling any pain when you wear shoes. If you were to walk barefoot on those surfaces, your feet would hurt—all because the nerves in your feet register the damage. If your nerves are ever impaired by something like peripheral neuropathy, however, you could incur serious damage without ever realizing it.
Blocked Nerves, Numb Feet
Peripheral neuropathy is a problem with impaired, misfiring nerves in the extremities. Nervous tissue is very sensitive. Different issues, from injuries to illnesses, can damage the tissue and cause it to stop functioning properly. Feet have a particularly high risk for this problem. Once the neuropathy develops, your feet are not as sensitive as they were. You end up with varying degrees of numbness, which can mean your feet don’t feel small injuries when they occur. Sometimes your feet burn and tingle as the nerves misfire and send wrong information to the brain. Shooting pain, weak muscles, and even an abnormal sensitivity to touch can also be signs of neuropathy.
