When Your Feet Stop Sending the Right Signals

Your feet constantly send information to your brain so you know when the floor is cold, your shoe is rubbing, or you step on something uncomfortable. But what happens when those messages become weaker, distorted, or disappear altogether?

For people living with diabetes, this can happen because of nerve damage known as diabetic neuropathy.

Your nerves are your feet’s warning system

Nerves act as a communication network between your feet and your brain. They let you feel pressure, temperature, pain, and touch, and help your body respond appropriately when something isn’t right.

When those nerves become damaged, the messages may no longer travel normally. Diabetic neuropathy most commonly affects the feet and lower legs and can develop gradually, so changes in sensation may be subtle at first. You might notice occasional tingling or a strange sensation in your toes before realizing that your feet don’t feel quite the way they used to.

How diabetes can affect the nerves

Over time, consistently high blood sugar levels can damage the small blood vessels that supply your nerves. This can interfere with how the nerves function and, eventually, lead to nerve damage. Not everyone experiences diabetic neuropathy in the same way. Some people experience pain or increased sensitivity, while others gradually lose sensation. That difference is important.

What do diabetic neuropathy symptoms feel like?

The symptoms can vary considerably. Some people describe a burning or tingling feeling, while others experience sharp, shooting or electric-like sensations. Feet may feel unusually sensitive to touch, or you may feel as though you are wearing socks when you are not.

For others, the biggest change is numbness. You may notice that you don’t feel temperature as clearly as before, or that pressure from your shoes isn’t as noticeable; a sensation that once caught your attention may barely register.

These are some of the common diabetic neuropathy symptoms to be aware of, but neuropathy can also occur without obvious symptoms.

When less pain can actually mean more risk

It may seem like having less foot pain would be a good thing, but when reduced pain is caused by nerve damage, it can remove one of your body’s most important warning systems. Imagine developing a blister from a new pair of shoes. Normally, the discomfort would encourage you to take your shoes off and investigate. If sensation is reduced, you might continue walking without realizing there is a problem. The same can happen with a small cut, pressure area or other injury. What starts as a minor problem can become more serious if you don’t notice and address it.

This is one reason diabetic foot care involves more than simply treating a problem once it appears. Understanding changes in sensation can help you recognize when your feet need attention.

Neuropathy and your overall foot health

Nerve damage is only one of the factors that can contribute to diabetic foot complications. Changes in circulation, skin health, pressure, and the body’s ability to heal can also play a role. This is why regular foot assessments can be valuable for people living with diabetes. A chiropodist can assess sensation and other aspects of foot health, identify areas of concern and help you understand how to protect your feet. The chiropodists at Werkman, Boven & Associates perform an annual diabetic assessment, or more often if required, and consolidate it into a report to send to your family physician so we can stay connected with your health team.

If you notice new or worsening numbness, tingling, burning, unusual sensitivity, or unexplained foot pain, don’t assume you have to live with it.

Your feet may be telling you something

Neuropathy can change the way your feet communicate with you. Sometimes the message is painful or uncomfortable. Other times, the most important message is the one you can no longer feel.

Knowing the diabetic neuropathy symptoms to watch for is an important part of understanding your foot health when you have diabetes. November is Diabetes Awareness Month, so it’s a good time to watch for changes in your feet and talk to your healthcare team about any concerns.

Your feet may not always tell you when something is wrong. Understanding how they communicate can help you protect them.
