At first, they seem like just a cosmetic concern. Many people leave them untreated for years because there's no discomfort. But over time, changes can start happening gradually. Are visible veins always harmless? Not always. While they may not hurt initially, they often indicate an underlying vein issue. What causes them? It usually comes down to vein valves not working properly. Blood starts pooling instead of flowing normally. Can it get worse over time? Yes. What starts as visible veins can gradually lead to heaviness, swelling, or skin changes if ignored. When should you get it checked? Even without pain, it's worth evaluating early. A specialist can assess whether treatment is needed. What are the treatment options? Today, many treatments are minimally invasive. Procedures like laser or VenaSeal are commonly used and don't require major surgery. If you've been noticing changes, you can consult Dr. Santosh B. Patil at Expert-IR and understand whether it needs treatment or just monitoring.
