SN instructed on intermittent claudication which is a condition caused by narrowing of the arteries that supply the legs with blood. Intermittent claudication causes pain in your calves when walking, Patients with intermittent claudication develop pain when they walk because not enough oxygen-containing blood reaches the active leg muscles. There are two main ways to treat claudication: medication and a surgical treatment, called revascularization. Medication therapies are often used initially as they are non-invasive. Compression therapy can also be used as a noninvasive way to treat symptoms of claudication. Intermittent calf compression has been shown in studies to improve symptoms-free walking distance.
