Swollen ankles is a symptom of kidney failure, a possible consequence of uncontrolled diabetes, reports the New York Times. Itching, fatigue and pale skin color are additional symptoms of kidney failure, which is a severe condition that requires medical attention.
Damage to the surrounding blood vessels and nerves cause diabetics to be more prone to various foot problems, explains the New York Times. Neuropathy is a common effect of long-term diabetes and causes numbness and tingling in the feet. This often leaves the individual unaware of the symptoms from other dangers that may be affecting his feet. Diabetics are advised to thoroughly inspect their feet daily to identify symptoms early.
