(HealthDay News) -- Varicose veins are enlarged, swollen veins in the legs that can be painful, although they're usually not serious.

The womenshealth.gov Web site says you should see a doctor about varicose veins if:

  • A vein becomes swollen, red, tender or feels warm.
  • Sores or a rash develop nearby.
  • Skin on the ankle or calf thickens and changes color.
  • The vein starts to bleed.
  • Symptoms hinder daily activities or cause emotional distress.
