Ask him: He feels you have diminished arterial blood flow and/or calcification of arteries evident on x-ray. Ask him and he will tell you why.

Circulation: Your circulation to your legs and or feet have decreased arterial flow. More common in smokers.

Possible diagnosis: Discuss that with your doctor. There must have been some tests done to come up with that diagnosis.
