Arterial blockage occurs when blood vessels narrow or become completely blocked by plaque buildup (cholesterol, fat) or blood clots, reducing oxygen-rich blood flow to organs. Prolonged blockage can lead to serious conditions like heart attack, stroke, and tissue damage, posing a life threat if not treated promptly. The following are leg symptoms that signal this condition.

leg pain

A common sign of poor circulation is pain or cramping in the calves or thighs that appears after walking a certain distance. This condition, known as intermittent claudication, occurs when narrowed arteries cannot deliver enough oxygen-rich blood to the muscles. If the pain starts rapidly or causes discomfort even at rest, it is crucial to check the peripheral arterial system and cholesterol levels.

leg fatigue

Persistent leg fatigue may indicate poor blood circulation. Cholesterol buildup restricts the oxygen and nutrients muscles need, making simple tasks like climbing stairs or walking long distances difficult. Over time, muscle strength can decline if blood flow remains impaired.

one leg colder than the other

A persistently cold foot or lower leg, especially after walking, often relates to reduced blood flow. Since blood carries heat, any interruption can make one side feel colder. In severe cases, the skin may appear pale or bluish when the leg is elevated.

tingling, numbness, or burning sensation in the feet

A "pins and needles" sensation, numb toes, or a burning feeling often occur when nerves do not receive enough oxygen-rich blood. Narrowed arteries impair nerve function, leading to prolonged loss of sensation. This increases the risk of slow-healing wounds or infections in the feet.

skin color changes after walking

Unusual skin changes in the legs, such as paleness, blotchy discoloration, or a bluish-purple tint, can indicate restricted blood circulation. In severe cases of peripheral artery disease, the skin on the legs often appears shiny, with reduced hair growth and slow-healing ulcers.

Individuals experiencing these symptoms should consult a doctor for diagnosis and timely treatment to prevent serious complications, including the risk of amputation.
