What Are Some Risks If I Dont Get Treatment

Diabetes-related foot pain is more than just pain its a warning sign from your body. This type of nerve pain can lead to complications if you dont see a doctor and get treated. Below are some of the problems that can come from untreated diabetes nerve pain:

  • Dry, cracked skin. This may not sound too bad, but when your skin is too dry, your risk of getting skin infections goes up. If this happens, plain petroleum jelly or unscented hand creams can help. Just avoid placing moisturizers between your toes.

  • . This is an area of thickened skin that has less feeling. People with diabetes get calluses faster and more often than those without diabetes. You can use a pumice stone daily to help keep them at a minimum. If they get really thick, a doctor can cut or shave them down. Never attempt to do this at home as it can lead to infections.

  • Ulcers. These are sores that happen to some people with diabetes due to poor blood circulation. All ulcers need to be seen by a doctor. The longer you go without seeing a doctor, the more likely it is that it will become infected. Infected ulcers can spread and cause you to lose your foot or leg.

  • Amputations. If the previously listed complications are not treated properly, they can all become infected. Skin infections can cause the skin and muscle tissues to die. Once this happens, it cant be fixed. The only way to stop the infection from continuing to spread is by amputating the infected limb.

Diabetes Causes Peripheral Vascular Disease

Diabetes accelerates the build-up of bad cholesterol in your vessels. It also damages the vessels and causes a decrease in the release of a chemical called nitric oxide, which functions to relax your blood vessels.

Furthermore, people with diabetes feet receive less blood supply than they actually should. Because of the shortage in the blood supply, the tissues in the feet start to die. It also slows down the healing process of wounds in the feet.

You may experience a few or several of the following problems due to diabetes:


  • Athletes foot: It is a condition in which fungus starts to grow between the toes of your feet. It causes pain, redness and cracking of the skin.
  • Corns: It is the formation of hard skin on the bony sides of the toes or in between the toes.
  • Blisters: These are the fluid-filled bubbles that may form on your feet either due to infection or due to wearing tight shoes.
  • Foot Ulcers: These are the most important foot-related complication of diabetes. These ulcers form from a wound that fails to heal properly.

In closing, if youre diabetic its recommended to check your feet often and if you see anything out of the ordinary contact your doctor immediately.

What Is Peripheral Vascular Disease

How Does Diabetes Affect Your Feet?

Diabetes is associated with poor circulation . Inadequate blood flow increases the healing time for cuts and sores. Peripheral vascular disease refers to compromised blood flow in the arms and legs. Poor blood flow increases the risk that infections will not heal. This, in turn, increases the risk of ulcers and dry gangrene, which is tissue death that occurs in a localized area when there is an inadequate blood supply.

How Does Diabetes Affect The Health Of My Feet

Diabetes-related foot pain is mainly caused by high blood sugar levels. Over time, high levels of sugar in the blood damage both the nerve endings and blood vessels throughout the body. This combination causes nerve pain and poor circulation.


The feet are especially prone to poor circulation because theyre so far away from the heart. Diabetes-related nerve pain can appear in the hands, but most people who experience it feel it in their feet first.

Other factors that can increase your risk of developing diabetes-related foot pain include being overweight, kidney disease, and smoking.

Diabetics Who Dont Receive Proper Treatment Often Experience Progressive Foot Trouble :

  • First, nerve damage leads to changes in gait and balance. This can alter pressure distribution and cause deformities.
  • If there is too much pressure or friction on specific points, the patient may develop corns and calluses.
  • Due to their compromised internal alarm system, the patient may not notice the callus and continue walking on it, causing a blister.
  • Pressure causes the skin to break, leaving a wound that gets deeper and deeper.
  • Some wounds dont heal and become chronic ulcers.
  • Diabetic foot ulcers are susceptible to infection.
  • If the infection becomes serious and spreads to the bone or if the patient develops gangrene due to poor circulation, the extremity may need to be amputated.
  • With proper care, this domino effect can often be stopped at almost any stage.

Good foot care is very important to prevent serious infections and gangrene.

    Wear shoes and socks at all times. Do not walk barefoot or in just socks even when you are indoors. You could step on something and hurt your feet. You may not feel any pain and may not know that you hurt yourself.

    Check the inside of your shoes before putting them on, to make sure the lining is smooth and free of pebbles or other objects.

    Make sure you wear socks, stockings, or nylons with your shoes to keep from getting blisters and sores. Choose clean, lightly padded socks that fit well. Socks with no seams are best.

    Wear shoes that fit well and protect your feet. Here are some tips for finding the right type of shoes:


    • Walking shoes and athletic shoes are good for daily wear. They support your feet and allow them to breathe.
    • Do not wear vinyl or plastic shoes, because they do not stretch or breathe.
    • When buying shoes, make sure they feel good and have enough room for your toes. Buy shoes at the end of the day, when your feet are the largest, so that you can find the best fit.
    • If you have a bunion, or hammertoes, which are toes that curl under your feet, you may need extra-wide or deep shoes.1 Do not wear shoes with pointed toes or high heels, because they put too much pressure on your toes.
    • If your feet have changed shape, such as from Charcots foot, you may need special shoes or shoe inserts, called orthotics. You also may need inserts if you have bunions, hammertoes, or other foot problems.
