Yes! Varicose veins are a clear sign of chronic venous insufficiency (CVI), meaning the “blood return pump” in your legs—the venous valves—has been damaged. Initially, they may appear as spider-like fine threads or twisted “worm-like veins.” However, without intervention, the condition will progressively worsen, potentially leading to leg heaviness, pain, itching, skin pigmentation, and even blood clots or non-healing ulcers. It is a clear health warning, not merely a cosmetic issue.
