Recognizing restricted circulation in your legs, often a sign of Peripheral Artery Disease (PAD) or venous insufficiency, involves watching for several key physical markers in 2026. Common symptoms include persistent numbness or "pins and needles" that doesn't resolve with movement, and a noticeable temperature difference where your feet or lower legs feel chronically cold compared to your torso. You may also observe skin changes, such as a shiny, tight appearance, or a bluish/pale tint, and slow-healing wounds on the feet. A hallmark sign is "claudication"—cramping or heavy pain in the calves that occurs during walking but subsides with rest. In 2026, medical professionals suggest the "capillary refill test": press firmly on a toenail until it turns white; if the pink color takes more than two seconds to return after you release it, your blood flow may be compromised.
