ENGLISH

Most varicose veins do not suddenly become emergencies, but some changes should not be ignored.

  • Redness, heat, pain or a firm cord
  • Sudden one-sided swelling
  • Brown or firm ankle skin
  • Bleeding or a slow-healing wound

1.Superficial vein inflammation

  • A vein may suddenly become red, hot and tender.
  • It may feel like a firm cord.
  • Assessment determines its extent and proximity to deep veins.

2.Skin change and wounds

  • Long-term pressure can darken ankle skin.
  • Skin may become itchy, thick or firm.
  • Severe disease may cause a slow-healing venous wound.
