Saw an intriguing case today. Would love your suggestions. 42-year-old doctor engaged in a sedentary job presented with c/o b/l pain in the legs below knee till ankle.

Pain has been present for the last 4-5 months and it starts from the first step of the day and persists all throughout the day. He claims that it gets better in cold environments. Smokes half a packet of cigarettes a day.
