Diabetes Leg Sores

Tingling sensation and numbness in the hands and feet are two main symptoms that indicate diabetes. Wounds, cuts and bruises often go undetected and take a long time to heal as a result of diabetes. Leg sores, commonly known as leg ulcers, occur on the legs in the area below the knee portion. They may cause pain, swelling, itching, rash, discoloration and scaly skin.

Leg ulcers are generally classified into three types. Diabetes leg sores or ulcers are the third type. They are also known as Neurotrophic leg ulcers. The increased pressure points in the feet are mainly affected. Any cuts or bruises o these points can go undetected and lead to infection if left untreated.


Diabetes affects blood circulation and the blood flow to the feet is also impaired. The nerve function is also affected and in case of any injury or bruise, the pain signals are not transmitted to the brain. This adds up to the numbness and tingling sensation.

This is how diabetes leg sores or ulcers form. The body’s response to fight the infection and heal the wound is also delayed. If the leg sores go undetected for a long time then the infection starts spreading to other healthy tissues surrounding the wound.

The leg sores appear as reddish/pink or brownish/black in color. In severe cases, amputation becomes necessary. This is also one of the leading cause for amputations in diabetics.


Diabetes leg sores can be prevented by following some basic precautionary measures. They are:

  • Wear clean shoes which fit comfortably.
  • Keep your feet clean and wash them with a mild soap and water regularly.
  • Pat dry your feet with a towel every time after a wash.
  • Avoid walking barefoot.
  • Do not apply and weight or pressure on the infected area.
  • Clean the wound regularly.
  • Visit a doctor or a podiatrist regularly to get the wound cleaned and dressed.
