Poor circulation is something that complicates many podiatry problems. When intermittent claudication sets in, its time for a vascular surgery consult. There is a recent post on Podiatry Arena (Intermittent claudication testing and differential diagnosis) with a question about the differential diagnosis of intermittent claudication. Musculoskleteal causes is probably the most common, but there are some others such as a compartment syndrome or a nerve entrapment. The treatment options these days are much better for those with peripheral vasucalr disease. The Foot Health Forum has a number of threads from people with poor circulation and it is always helpful to peruse them to see what people with the condition actually think about their problems.
