Complications

By Mayo Clinic staff

Complications of varicose veins, although rare, can include:

  • Ulcers. Extremely painful ulcers may form on the skin near varicose veins, particularly near the ankles. Ulcers are caused by long-term fluid buildup in these tissues, caused by increased pressure of blood within affected veins. A brown colored 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 swell considerably. Any sudden leg swelling warrants urgent medical attention because it may indicate a blood clot — a condition known medically as thrombophlebitis.
