What causes leg pain when walking?

Pain that appears after a predictable amount of walking and eases with rest can occur when leg muscles do not receive enough blood during activity, a pattern called intermittent claudication. Peripheral arterial disease is one possible cause. Calf pain with swelling, warmth, or skin colour change can point to a vein problem and needs prompt review. Arthritis, tendon strain, footwear, and nerve irritation from the back can cause pain with a different pattern. Diabetes can affect circulation and nerves, so foot symptoms deserve attention.

Note where the pain starts, how far you can walk before it appears, whether rest relieves it, and whether numbness, swelling, or skin changes occur. Arrange an assessment for recurring or worsening pain. A clinician may examine pulses, skin, joints, nerves, and walking pattern. Do not smoke, and follow advice about activity, blood pressure, cholesterol, or diabetes if relevant to you.

Seek urgent help for sudden severe leg pain, a cold or pale foot, new weakness, loss of sensation, or inability to walk. One-sided swelling with warmth or tenderness needs prompt assessment, especially with sudden breathlessness or chest pain. A wound on the foot that is not healing also warrants timely medical care.

Ask whether the pattern suggests arteries, veins, joints, muscles, or nerves. Ask whether circulation and diabetes checks are needed, which activity is safe, and which changes should trigger urgent care.
