رجل عمره ٦٦ سنة مدخن ومصاب بالسكري، يشتكي ألماً في ساقه عند المشي ١٠٠ متر يزول بالراحة خلال دقائق. الجلد على الساق لامع بدون شعر، والنبض القدمي ضعيف، ولا يوجد ألم في الراحة أو قرح. أي نصيحة صحيحة؟

A 66-year-old diabetic smoker reports calf pain after walking 100 metres that settles within minutes of rest. The leg skin is shiny and hairless, foot pulses are weak, and there is no rest pain or ulcer. Which advice is correct?

1. Elevate the legs above heart level all night
2. Walk daily until pain starts, rest, then continue
3. Wear tight compression stockings all day
4. Avoid walking altogether to prevent further damage

Answer: B) Walk daily until pain starts, rest, then continue. This is intermittent claudication from peripheral arterial disease. A regular walking programme improves collateral flow and walking distance. Elevation and tight compression reduce arterial perfusion and suit venous problems.
