What Are Varicose Veins and How Are They Treated?

Updated

Varicose veins are enlarged, bulging veins that most often appear on the legs. They develop when blood pools in a vein instead of flowing back to the heart efficiently, a problem commonly described as venous reflux. Spider veins are a related but milder concern: smaller, web-like veins near the skin surface. If you have bulging veins, leg heaviness, or skin changes, a vein specialist can confirm the cause and discuss treatment options ranging from compression and sclerotherapy to endovenous ablation and surgery.

What varicose veins are

Veins carry blood back to the heart. In the legs, that means moving blood upward against gravity. Small valves inside the veins normally keep blood from flowing backward. When those valves weaken or fail, blood collects in the vein, which stretches and bulges over time.

Varicose veins and spider veins are both vein-related conditions, but they differ in size and appearance:

Feature Varicose veins Spider veins
Appearance Bulging, twisted, rope-like Fine, web-like, close to the skin
Typical location Legs, especially thighs and calves Legs, face, and other areas
Usual symptoms Heaviness, aching, swelling, fatigue Often cosmetic, sometimes mild discomfort
Main concern Can progress and cause skin changes Usually cosmetic

Why they happen

The underlying mechanism is venous reflux — blood flowing the wrong way through a faulty valve. Vein Directory lists venous reflux as a core condition to understand, alongside venous disease generally.

Factors that raise the likelihood of developing varicose veins include:

  • Genetics — a family history of vein problems
  • Prolonged standing or sitting — jobs or routines that keep legs still for long periods
  • Age — valve function tends to weaken over time
  • Weight and pregnancy — added pressure on leg veins
  • Diabetes — Vein Directory covers vein care and diabetes as a related topic, so it is worth raising with a clinician if you manage the condition

Symptoms and warning signs

Many people notice varicose veins before they cause real trouble. Common experiences include:

  • Visible bulging or twisting veins
  • Legs that feel heavy, tired, or achy, often worse at the end of the day
  • Swelling in the ankles or lower legs
  • Itching or burning around the vein
  • Night cramps

Seek medical attention rather than waiting if you notice:

  • Skin changes such as discoloration, thickening, or a shiny, tight look
  • A sore or ulcer on the leg that will not heal
  • Sudden swelling, redness, warmth, or pain in one leg
  • Bleeding from a vein

These can point to more advanced venous disease and should be evaluated by a professional.

Treatment options

Treatment falls into a few broad categories, from conservative management to procedures. Vein Directory organizes its treatment information around these groups:

Non-invasive and preventive

  • Compression socks and stockings, which support the vein and reduce symptoms at home
  • Leg elevation, movement, and weight management as everyday habits

Minimally invasive procedures

  • Sclerotherapy — an injection that closes smaller veins, commonly used for spider veins and some varicose veins
  • Endovenous ablation — heat-based treatment (endovenous thermal ablation) that seals a faulty vein from the inside
  • VenaSeal closure system — a closure approach listed among treating-veins options
  • Laser and light treatments — used for certain vein types

Surgical options

  • Phlebectomy — removal of bulging veins through small incisions
  • Varicose vein surgery — for cases not suited to less invasive methods

Other areas

  • Deep venous treatments, for problems in the deeper vein system
  • Treatments around the eyes, a separate category Vein Directory covers

Which option fits depends on the vein's size, location, and whether reflux is present. A specialist typically confirms this with an evaluation before recommending a path.

When and how to find a vein specialist

Consider seeing a specialist if symptoms interfere with daily life, if you notice warning signs like skin changes or non-healing sores, or if you want a clear diagnosis before deciding on treatment.

Vein Directory is an online directory and resource for people with varicose veins and vein-related conditions. You can use it to:

  1. Search by location or name — find a vein and lymphatic specialist near you using the directory's search tools
  2. Ask a doctor — post a question and get answers from physician members
  3. Read articles and Q&A — browse conditions, prevention and management, and treating-veins sections
  4. Review before-and-after photos — see examples tied to specific doctors

When choosing a doctor, look for someone who specializes in vein treatment, confirm they offer the procedure relevant to your case, and ask how they evaluate venous reflux before recommending treatment.
