Skin signs are commonly found over the shins and appear as brown scars. The brown spots may be preceded by red or blistering spots. The cause is due to abnormal changes of small blood vessels in the skin. There is no specific treatment for this skin disorder. The condition tends to heal by itself into depressed scars.
Severe occlusion can lead to gangrenous changes of the toes as a result of tissue death.
Surgery will be needed to remove the dead tissues and in severe cases, amputation of the foot or leg. This can cause a burning and tingling sensation and numbness of the feet. Patients also have reduced or loss of pain sensation and may develop skin sores and ulcers on the feet due to trauma if good foot care is not instituted. Diabetics are more prone to skin infections. Examples are styes, boils and fungal infection.
