Faulty one-way valves allow blood to pool in the lower limbs, leading to swelling, aching, skin damage and, in advanced cases, non-healing ulcers. The condition affects up to 40% of adults, yet many people dismiss the early warning signs until complications develop.

(CVI) or venous reflux disease\u2014occurs when leg veins can\u2019t push blood back to the heart efficiently. Faulty one-way valves allow blood to pool in the lower limbs, leading to swelling, aching, skin damage and, in advanced cases, non-healing ulcers.
