High cholesterol symptoms: Six 'physical' signs in your feet warning of high levels - CDC

High cholesterol means you have too much cholesterol - a waxy substance produced inside the liver - in your arteries. Cholesterol is needed to build healthy cells but having too much of it can clog up your arteries. Unfortunately, symptoms do not typically arise until high cholesterol causes complications.

Peripheral arterial disease (PAD) is a manifestation of cholesterol build-up.

PAD in the legs or lower extremities is the narrowing or blockage of the vessels that carry blood from the heart to the legs.

It is primarily caused by the buildup of fatty plaque, such as cholesterol, in the arteries, which is called atherosclerosis.

PAD can happen in any blood vessel, but it is more common in the legs than the arms.
