Varicose Ulcer Causes
Varicose ulcer causes are often linked to long-term vein problems that affect blood flow in the legs. When veins struggle to move blood back toward the heart, pressure builds up in the lower legs over time. This ongoing pressure can weaken the skin, making it thin, fragile, and slow to heal. Even a small cut or scratch may turn into an open sore known as a varicose ulcer.
