Peripheral artery disease (PAD) affects an estimated 10 to 12 million U.S. adults over 40, according to the American Heart Association. Many never recognize the disease because its early signs are easy to write off as sore muscles or getting older.
That gap matters. PAD is plaque buildup in the arteries that carry blood to the legs, and the same disease process tends to affect the arteries supplying the heart and brain.
Anyone with PAD therefore carries a higher risk of heart attack and stroke, according to the National Heart, Lung, and Blood Institute (NHLBI).
What claudication actually feels like
The most talked-about symptom of PAD is claudication, meaning muscle pain, cramping or heaviness in the calf, thigh or buttock that shows up during walking and eases within a few minutes of rest.

The NHLBI notes that only about one in four people with PAD experience this classic pattern. Many others have milder signs or none at all, which is a large reason the disease is so often missed.
Vascular surgeon Dr. Matthew Cindric of Penn State Health has described it as a life-shrinking problem. "We consider claudication a lifestyle-limiting condition," he told Penn State Health News, noting that patients often stop walking distances they used to manage comfortably.
7 warning signs to know
The American Heart Association highlights seven signs that reduced blood flow to the legs can produce. Any of them, especially in combination, is worth raising with a healthcare provider.
Leg pain, cramping or heaviness during walking that eases with rest
Coldness or numbness in one foot or the lower leg, particularly compared with the other side
Sores on the toes, feet or legs that heal slowly or not at all
Shiny skin, or a change in color, on the legs or feet
Hair loss or slower hair growth on the lower legs

Tingling or burning in the lower legs and feet
Some people also notice slower toenail growth, and in men PAD can cause erectile dysfunction. Symptoms alone are not enough to rule the disease out.
Why early diagnosis matters
Untreated PAD can lead to non-healing wounds and, in serious cases, amputation. It also flags widespread atherosclerosis in the body, which is why the AHA describes timely diagnosis and coordinated care as essential to prevent amputation and other cardiovascular complications.

Treatment usually starts with the basics that also protect the heart. That means stopping smoking, controlling blood pressure, cholesterol and diabetes, and building walking tolerance under medical guidance.
Heather Gornik, M.D., of University Hospitals Harrington Heart & Vascular Institute, who chaired the AHA's PAD guideline, has said supervised exercise therapy is the gold standard for PAD and is "woefully underutilized despite its known health benefits."
When to talk to a doctor
Anyone with these symptoms should see a healthcare professional. That goes double for people who smoke or have smoked, have diabetes, high blood pressure or high cholesterol, or are over 50.
Cindric put it plainly to Penn State Health News. "Vascular problems tend to escalate rapidly without prompt diagnosis and intervention, particularly in patients who have wounds on the feet that won't heal."

A simple, painless in-office test called the ankle-brachial index, which compares blood pressure at the ankle with pressure at the arm, is often the first step in confirming the diagnosis.
