Its a very uncomfortable and unpleasant situation: the loss of feeling on your feet.
Not being in a position to sense or really feel whether the ground is very hot or freezing cold, or whether your footwear don’t fit right. Or worse, not realizing the injury and harm you could be causing to your feet.
“When you realize you’ve lost pain, you are in trouble,” says Dr. Andrew Boulton, professor of medicine in the division of endocrinology, diabetes and metabolism of the University of Miami Miller School of Medicine.
Boulton has witnessed the consequences of not feeling foot pain.
The individual who walked around without having noticed he had a nail through his shoe. Another one who took a stroll on the beach not realizing the hole slowly carved on his foot by the hot sand. Or the man who felt asleep near a chimney and woke up to the smell of something burning his feet.
Boulton is an expert on neuropathy, a disease prompted by poor glucose control, among other factors. The condition causes nerve damage, impairing feeling in the foot.
Neuropathy acts similarly to an electrical circuit being disrupted. The nerves send messages to your brain about heat, cold, touch and pain. Nerves communicate how and when to move your muscles, and also have control over systems like sweat glands or digestive functions. So when these nerves are damaged, communication stops.
