3. Leg Pain or Cramping When Walking

This is one of the more characteristic signs of peripheral artery disease (PAD).

PAD occurs when arteries supplying the legs or other extremities become narrowed, most commonly because of atherosclerosis.

A person with PAD may develop aching, cramping, burning, heaviness or fatigue in the legs while walking or climbing stairs.

The pain often improves after stopping and resting for several minutes.

This pattern is called intermittent claudication.

For example, someone might walk several blocks before developing calf pain. They stop, rest, and the pain improves. When they start walking again, the pain returns.

That pattern is worth discussing with a healthcare professional.

Don’t assume it’s simply aging

Leg discomfort is often attributed to arthritis, muscle problems or getting older.

But PAD can produce a very specific pattern of pain related to physical activity.

If you repeatedly experience leg pain during walking that improves with rest, don’t simply ignore it.

4. Feet or Legs That Feel Colder Than Usual

Reduced circulation can sometimes cause one foot or lower leg to feel cooler than the other.

This is particularly relevant when the change occurs together with other symptoms such as leg pain, changes in skin color or slow-healing wounds.

The American Heart Association lists a cooler temperature in one foot or lower leg among possible signs of PAD.

However, simply having cold feet does not prove that you have blocked arteries.

Cold temperatures, circulation differences, certain medications and many other conditions can cause cold hands or feet.

The important thing is to pay attention to persistent or one-sided changes, especially when they occur with other circulation symptoms.

5. Wounds That Heal Slowly

A cut, blister or sore on your foot that takes an unusually long time to heal can sometimes indicate reduced blood flow.

Your tissues need adequate blood and oxygen to repair themselves.

In PAD, reduced circulation can make wounds on the feet or legs slow to heal. In more advanced disease, wounds may become serious and tissue damage can occur.

This is especially important for people who have other cardiovascular risk factors.

Don’t ignore:

A foot ulcer that doesn’t heal
A recurring sore
A wound that keeps getting worse
Skin breakdown around the toes
A wound accompanied by unusual coldness or discoloration

A slow-healing wound does not automatically mean an artery is blocked, but it deserves appropriate medical evaluation.

6. Changes in Skin Color

Reduced circulation can sometimes cause visible changes in the skin of the feet or legs.

The skin may appear unusually pale when the leg is raised and become redder when the leg is lowered. Other forms of discoloration can also occur depending on the severity and cause of the circulation problem.

Again, skin color alone isn’t enough to diagnose PAD.

But if you notice a persistent change—particularly in combination with pain, coldness, wounds or reduced sensation—it is worth getting checked.

7. Slow-Growing Toenails or Less Hair on the Legs

This is a less commonly recognized possible sign of poor circulation.

The American Heart Association lists slow-growing toenails and reduced hair growth on the legs among possible changes associated with PAD.

The explanation is related to reduced blood supply to tissues in the legs and feet.

However, these signs aren’t specific to blocked arteries. Hair growth and nail growth can change for many reasons.

So don’t look at your toenails or leg hair and conclude that you definitely have arterial disease.

Instead, consider the whole pattern.

If these changes occur together with exertional leg pain, cold feet or poorly healing wounds, talk with a healthcare professional.

8. Sudden Weakness, Numbness or Trouble Speaking

When narrowed or blocked arteries affect blood flow to the brain, the consequences can be much more serious.

Carotid artery disease, for example, can be associated with a transient ischemic attack (TIA) or stroke.

Warning symptoms can include:

Sudden weakness or numbness on one side of the body
Sudden facial weakness
Difficulty speaking
Difficulty understanding speech
Sudden vision problems
Sudden dizziness
Loss of balance
A sudden severe headache

The American Heart Association notes that these can be warning signs of a TIA or stroke.

This is an emergency

If these symptoms occur suddenly, don’t wait to see whether they disappear.

Even if symptoms improve after a few minutes, a TIA can be a warning that a stroke could occur.

Emergency medical attention is appropriate.

9. Temporary Vision Loss

Sudden vision changes can also be associated with reduced blood flow to the brain or eyes.

For example, carotid artery disease can cause temporary vision loss in one eye. The American Heart Association lists sudden vision loss or blurred vision among possible warning signs of carotid artery disease.

A person might describe it as a curtain or shadow coming over part of their vision.

This should never simply be dismissed as tired eyes.

Sudden vision loss can have several serious causes, and urgent medical assessment is important.
