The headline “10 indicators of blocked arteries you shouldn’t ignore” is a little misleading because artery narrowing can cause no symptoms at all, especially early on. The symptoms depend on which arteries are affected.

10 possible warning signs
Chest pressure, squeezing, or pain — may occur when the heart isn’t receiving enough blood.
Shortness of breath — especially with exertion or together with chest discomfort.
Pain or discomfort in the arm or shoulder — particularly when accompanied by chest symptoms.
Jaw, neck, or back discomfort — these can accompany reduced blood flow to the heart.

Unusual dizziness or light-headedness — particularly with other heart symptoms.
Leg pain or cramping when walking — a classic symptom of peripheral artery disease (PAD); it typically improves after resting.

Leg or foot weakness, numbness, or tingling — can occur when circulation to the limb is reduced.

A foot or leg that is unusually cold, pale, blue, or discolored — reduced arterial blood flow can produce these changes.

Sores on the feet or legs that heal very slowly — impaired circulation can make wounds difficult to heal.

Reduced walking ability, or pain in the legs at rest/night — can indicate more significant PAD.

🚨 Don’t wait with these symptoms
Chest pain/pressure, severe shortness of breath, fainting, or pain spreading to the arm, jaw, neck, or back can be signs of a heart attack. Call your local emergency service rather than trying to determine whether an artery is “blocked” at home.

Likewise, a suddenly cold, pale/blue, extremely painful or numb limb requires urgent medical attention.
The good news is that artery disease can often be detected and managed before a major event. Doctors may assess blood pressure, cholesterol, blood sugar, cardiovascular risk, and—when appropriate—use tests such as an ankle-brachial index (ABI) for suspected PAD.

Important: You cannot reliably diagnose a blocked artery from symptoms alone, and having one of these symptoms doesn’t necessarily mean an artery is blocked.
