You are walking through the grocery store when something strange happens.
Your calf begins to ache. At first, it feels like an ordinary muscle cramp. But the farther you walk, the more uncomfortable it becomes.
You stop for a moment, and the pain gradually disappears.
A few minutes later, you start walking again.
And the pain returns.
Many adults over 50 assume this is simply part of getting older. Others blame arthritis, muscle fatigue, or a lack of exercise.
But recurring leg pain during walking can sometimes be a warning sign of a condition called peripheral artery disease (PAD).
PAD occurs when arteries supplying blood to the legs become narrowed, most commonly because of a buildup of fatty deposits known as plaque.
Over time, reduced blood flow can affect walking, wound healing, and overall cardiovascular health.
What makes this condition particularly concerning is that some people have very mild symptoms—or none at all.
Here are seven warning signs worth knowing, what they may mean, and when to seek medical attention.
1. Leg Pain That Appears When Walking and Disappears With Rest
One of the classic symptoms of peripheral artery disease is called intermittent claudication.
This refers to muscle discomfort that develops during physical activity and improves after resting.
It commonly affects the calves but may also occur in the thighs, hips, or buttocks.
The discomfort may feel like cramping, aching, tightness, heaviness, or fatigue.
Why does this happen?
When you walk, your leg muscles need more oxygen-rich blood.
If the arteries are narrowed, they may be unable to deliver enough blood to meet that increased demand.
The result is muscle discomfort.
When you stop walking, your muscles require less oxygen, and the pain may subside.
A particularly important clue is pain that repeatedly appears after walking a similar distance and improves within several minutes of rest.
However, not all leg pain is caused by PAD.
Arthritis, spinal stenosis, nerve compression, and muscle problems can produce similar symptoms.
If this pattern occurs repeatedly, arrange a medical assessment.
2. One Foot Feels Colder Than the Other
Have you noticed that one foot frequently feels colder than the other?
Cold feet can have many explanations, including environmental temperature and normal differences in circulation.
But a persistent temperature
