10 Causes of Paresthesia
Reviewed: Dr. Gromatzky
Cause #4: Peripheral Artery Disease
Peripheral artery disease is a disorder where there is narrowing of arteries besides those in the heart (coronary artery disease) or brain (cerebrovascular disease). It most commonly affects the legs, resulting in leg pain when walking (intermittent claudication), cold skin, bluish skin, skin ulcers, and abnormal hair or nail growth.
Paresthesia is also a possible symptom due to poor circulation in the limbs. Without a proper supply of nutrients and oxygen from the blood vessels, the nerve cells are unable to send proper signals to the brain. Risk factors for peripheral artery disease include diabetes, cigarette smoking, high blood pressure, high cholesterol, and kidney issues.
