Complications

Complications of varicose veins, although rare, can include:

• Ulcers. Painful ulcers may form on the skin near varicose veins, particularly near the ankles. A discolored spot on the skin usually begins before an ulcer forms. See your doctor immediately if you suspect you've developed an ulcer.
• Blood clots. Occasionally, veins deep within the legs become enlarged. In such cases, the affected leg may become painful and swell. Any persistent leg pain or swelling warrants medical attention because it may indicate a blood clot — a condition known medically as thrombophlebitis.
• Bleeding. Occasionally, veins very close to the skin may burst. This usually causes only minor bleeding. But any bleeding requires medical attention.
