Noticing purple or bluish veins on your legs is common and often linked to varicose or spider veins, which occur when vein walls weaken or valves fail to push blood efficiently back to the heart. While these visible veins are sometimes just cosmetic, they can also signal circulation problems like chronic venous insufficiency, especially if accompanied by pain, swelling, heaviness, itching, or skin changes. Factors such as prolonged sitting or standing, lack of exercise, pregnancy, obesity, aging, and genetics all increase risk. If symptoms persist or worsen, a medical evaluation can help identify the cause early and prevent complications.
