Risk Factors

Superficial thrombophlebitis is more common in women. The risk is higher in those aged 60 years or older. Other things that raise the risk are:

  • History of vein problems or blood clotting problems
  • Long term bed rest or sitting
  • Obesity
  • Pregnancy
  • An IV, injury, or recent surgery
  • Certain cancers
  • Birth control pills or hormone replacement therapy
  • Immune system problems


Symptoms of superficial thrombophlebitis may be:

  • A vein that looks like a cord
  • Redness, warmth, and tenderness around the vein
  • Swelling around the vein

It can lead to problems such as:


The doctor will ask about symptoms and health history. A physical exam will be done.

Superficial thrombophlebitis often goes away on its own in a few weeks. If needed, treatment may involve:

  • Wearing compression stockings—to improve blood flow in legs
  • Exercise
  • Medicines such as:
    • NSAIDs, like ibuprofen—to ease pain and inflammation
    • Blood thinners
  • Procedures to remove the blood clot—if the problem gets worse or returns


The risk of having this problem may be lowered by:

  • Walking around the cabin every hour—when flying
  • Pulling over every hour or so and stretching—when driving long distances
