When to worry about leg pain when walking with peripheral arterial disease

Peripheral arterial disease narrows arteries supplying the legs. Muscles may ache, cramp, or feel heavy during walking because they need more blood flow, then improve after stopping. Pain may occur in the calf, thigh, buttock, or foot. A change in the distance you can walk, pain that starts at rest, or symptoms in one foot can indicate worsening circulation.

Other problems, including nerve irritation, joint disease, or a muscle injury, can also cause leg pain. A clinician can check pulses, skin, sensation, and walking symptoms to decide whether further assessment is needed.

Keep a record of where the pain starts, how long walking takes to bring it on, and how quickly it settles. Follow your prescribed medicines and attend circulation reviews. If a clinician has recommended a supervised walking programme, follow its pacing guidance and stop for concerning symptoms. Protect your feet from cuts, blisters, burns, and poorly fitting shoes, and seek advice about any wound that is slow to heal.

Arrange prompt review if walking pain is becoming more frequent, begins with less activity, lasts longer after stopping, or prevents normal daily tasks. Seek emergency help for sudden severe leg or foot pain, a cold or pale foot, blue or black skin, new numbness or weakness, or a wound with spreading redness, swelling, pus, or fever. Do not wait for a routine appointment when circulation appears suddenly reduced.

Ask whether your pain pattern suggests reduced circulation or another cause, how to exercise safely, and how to check your feet each day. Discuss smoking support if relevant, your medicine plan, warning signs of reduced blood flow, and who to contact if a foot wound changes.
