The key is D. Atherosclerosis. [i) It is not sciatica as sciatica pain is worse when sitting. There may be

weakness, numbness, difficulty moving the leg or foot. A constant pain on one side of the rear. A

shooting pain that makes it difficult to stand up. ii) It is not DVT as no swelling, warmth or redness of

skin are there iii) It is not thromboangitis obliterans as pulses are ok, no colour change or reduced hair

growth, no ulceration or gangrene iv) not embolism as no pain (rest pain), no numbness, not pale or

blue, no rash, no ulceration of skin].
