I always say that if you are a diabetic, it should be part of your routine. Most patients who have diabetes and a manifestation of diabetes (poor circulation or nerve damage) need to be seen for "at risk" care every 9 weeks. This include removing calluses and trimming nails to prevent ulcerations and infection.  Some patients with diabetes have great circulation and sensation in their feet and these patients need to see their podiatrist once every year, unless a new problem arises!
