What Are Spider Veins? 

Spider veins are similar to varicose veins and occur near the surface of the skin. Small and threadlike, they often look like spider webs or tree branches, and can be red, blue, or purplish in color. They can cover a small or large area of skin, and may enlarge over time. For some, spider veins are a cosmetic issue, but they can also cause throbbing, aching, and itchy legs.

What Are The Symptoms of Spider Veins?

  1. Painful veins
  2. Leg fatigue, heaviness, swelling, itching, and/or burning
  3. Skin discoloration


Varicose vein symptoms usually get worse as the day progresses, and may be relieved somewhat by leg elevation and aerobic activity. Even those without visible varicose veins may still be symptomatic due to non-visible dilated veins exerting pressure on nerves.

Why Do Spider Veins Usually Appear In The Legs?

Most spider veins appear in the legs due to the pressure of body weight, gravity, and the task of carrying blood from the bottom of the body up to the heart. Compared with other veins in the body, leg veins have the toughest job since they endure the most pressure.

What Causes Spider Veins?

Spider veins often appear in combination with varicose veins and share the same underlying causes.


  1. Family history
  2. Age
  3. Standing or sitting for long periods
  4. Pregnancy
  5. Hormonal changes
  6. Obesity
  7. Sun exposure
  8. Injuries

What Is The Treatment for Spider Veins?

At Metro Vein Centers, we offer several vein treatment options for spider veins using the latest technology.

Can Spider Veins Return After Treatment? 

Current treatments for spider veins have very high success rates compared to traditional surgical treatments. Over a period of years, however, more abnormal veins can develop as there is no cure for weak vein valves. Ultrasound can be used to keep track of how badly the valves are leaking (venous insufficiency). Ongoing treatment can help keep this problem under control.
