RFA varicose veins treatment is a modern option for people who want relief from leg discomfort without undergoing traditional surgery. Varicose veins often cause aching, swelling, tightness, or a heavy feeling in the legs, especially after long periods of standing. Radiofrequency ablation, commonly known as RFA, works by using gentle heat to close the damaged vein from the inside, allowing blood to naturally flow through healthier veins.
