Intermittent claudication is a cramping pain or tightness in the calf, thigh or buttock that comes on after walking a certain distance and eases within a few minutes of resting. It is caused by narrowing of the arteries that supply the legs, known as peripheral arterial disease. It needs a GP assessment, because it signals a higher risk of heart disease and stroke, and supervised walking exercise is one of the most effective treatments.
Also known as peripheral arterial disease, PAD, peripheral vascular disease, claudication
Anatomy: where the problem is
Side view of the lower leg. Highlighted in the diagram: arteries of the leg.
Symptoms
- Cramping, aching or tightness in the calf that comes on with walking
- Pain that comes on after a similar distance each time, sooner uphill or when walking fast
- Pain that eases within a few minutes of standing still
- Sometimes pain in the thigh or buttock instead
- Cold feet, hair loss on the lower legs or slow-healing sores on the feet
- Pain in the feet at rest or at night in more advanced disease
Causes and risk factors
- Fatty deposits narrowing the leg arteries
- Smoking, which is the most important risk factor
- Diabetes
- High blood pressure and high cholesterol
- Increasing age
- A family history of heart or circulation disease
What the evidence says helps
- See your GP for a diagnosis. Peripheral arterial disease is confirmed by examining the pulses and comparing the blood pressure at the ankle and the arm.2
- NICE recommends a supervised exercise programme for everyone with intermittent claudication: around two hours a week for three months, walking to the point of maximal pain.2
- A Cochrane review of 32 trials found that exercise programmes clearly improved how far and how long people could walk compared with usual care.1
- Reducing the risk of heart attack and stroke is equally important: stopping smoking, and medicines for cholesterol, blood pressure and blood clotting as advised by your GP.2
- Procedures to open or bypass the narrowed artery are considered if exercise and risk-factor treatment have not helped enough.2
Things you can try at home
- See your GP if you have calf pain on walking that settles with rest
- If you smoke, get support to stop: it is the single most effective step
- Walk regularly, at a pace that brings on the pain, rest until it eases, then continue
- Build up to at least 30 minutes of walking, three to five times a week
- Check your feet daily for cuts, sores and colour changes, especially if you have diabetes
- Take prescribed medicines for cholesterol, blood pressure and circulation
When to get urgent help
Contact your GP urgently, call NHS 111, or call 999 in an emergency if you have:
- A leg or foot that suddenly becomes cold, pale, numb or very painful: call 999
- Pain in the foot at rest or at night, or a sore on the foot that will not heal: see a GP urgently
- Chest pain, or sudden weakness, slurred speech or facial droop: call 999
- Calf pain with swelling, warmth and tenderness in one leg: get same-day medical help
- Calf pain on walking that is new: see your GP for assessment
How Apollo can help
Calf pain when walking has several causes, including the arteries, the spine and the calf muscles, and we assess which fits best. If your symptoms and pulses suggest a circulation problem, we write to your GP so that you can be assessed and treated. Once you have a diagnosis, our clinical exercise team can support you with a structured, progressive walking and strengthening programme in line with NICE guidance, and our free community walking group is a friendly way to keep the habit going.
No GP referral needed. Clinics in Sheringham, Coltishall and Norwich.

Frequently asked questions
Is it safe to walk if it brings on the pain?
Yes, once your GP has confirmed the diagnosis. Walking until the pain builds, resting and then continuing is the basis of the recommended exercise programmes, and it improves walking distance over time. It does not damage the leg.
How is claudication different from spinal stenosis?
Both cause leg pain when walking. Pain from narrowed arteries eases quickly on standing still. Pain from spinal stenosis usually eases only on sitting or bending forward, and is often accompanied by back pain or tingling. A clinician can check which is more likely.
Will I need an operation?
Most people do not. Exercise, stopping smoking and medicines are the main treatments. Procedures to widen or bypass the artery are considered when symptoms remain limiting despite these measures.
