The combination of fever and high blood sugar often warns of a severe infection requiring hospitalization. Lesser degrees of infection are often treated on an outpatient basis. Foot Deformities Foot deformities such as hammertoes, bunions, and metatarsal disorders have special significance in the diabetic population. Neuropathy places the foot at increased risk for developing corns, calluses, blisters and ulcerations. If these are left untreated, serious infections may result.
Special deformities can occur in persons with neuropathy and very good circulation.
A Charcot joint, resulting from trauma to the insensitive foot, causes the foot to collapse and widen. This destructive condition is often first heralded by persistent swelling and redness, mild to moderate aching, and an inability to fit into your usual shoes. If this occurs, it is important to stay off the foot and see your podiatric surgeon immediately. An ulceration or ulcer is usually a painless sore at the bottom of the foot or top of the toes, resulting from excessive pressure at that site. Ulcers frequently underlie a pre-existing corn or callus that was allowed to build up too thickly.
