What varicose veins are and why they happen

Varicose veins are swollen, twisted veins that usually appear on the legs and feet. They happen when the one-way valves inside your veins weaken or fail, allowing blood to pool instead of flowing back to your heart. The pooled blood makes the vein enlarge and become visible through the skin, often appearing blue or purple and bulging outward.

Several factors increase your risk: family history of varicose veins, age over 50, pregnancy, prolonged standing or sitting, obesity, and previous blood clots or leg injury. Women are more likely to develop them than men. The condition is common—roughly one in four adults has varicose veins—but severity varies widely. Some people have no symptoms beyond appearance; others experience pain, swelling, heaviness, or skin changes.

Key Takeaways

  • Varicose veins form when vein valves fail and blood pools, causing visible swelling; they are common but not always painful or dangerous.
  • Self-care measures like compression stockings, leg elevation, and movement can reduce symptoms and slow progression without medical intervention.
  • Medical treatments range from minimally invasive procedures (sclerotherapy, laser, radiofrequency ablation) to surgical removal, depending on severity and location.
  • Insurance coverage varies by plan and whether the procedure is considered cosmetic or medically necessary, so check your policy before pursuing treatment.
  • Complications like blood clots or skin ulcers are uncommon but require prompt medical attention if they occur.

When varicose veins need medical attention

Many people with varicose veins never need treatment. If the veins cause no pain, swelling, or skin changes, and you are comfortable with their appearance, observation is a reasonable choice. However, you should see a doctor if you experience leg pain, swelling that worsens by evening, skin discoloration or thickening around the vein, or open sores near the ankle. These signs suggest the vein is affecting circulation or skin health.

A doctor—usually a primary care physician or a vascular specialist—can examine your legs and may order an ultrasound to map blood flow and rule out blood clots. This imaging takes 15 to 30 minutes and is painless. If you have a family history of blood clots or have had one before, mention it, because varicose veins slightly increase clot risk in some people.

Self-care and non-medical management

Before pursuing any procedure, try these steps: wear compression stockings (available over-the-counter in varying pressure levels), elevate your legs above heart level for 15 minutes several times a day, move regularly to keep blood flowing, and avoid prolonged standing or sitting. These measures do not cure varicose veins but often reduce pain and swelling and may slow their progression.

Weight management, staying hydrated, and avoiding tight clothing around the legs also help. Some people find relief from over-the-counter pain relievers like ibuprofen when discomfort flares. If symptoms improve with these steps and appearance is not a concern, you may not need further treatment. Many people manage varicose veins this way for years.

Minimally invasive procedures

Sclerotherapy is the most common outpatient procedure. A doctor injects a chemical solution directly into the vein, which irritates the vein wall and causes it to collapse and fade. The procedure takes 15 to 45 minutes depending on how many veins are treated. You can return to normal activity the same day, though you must wear compression stockings for one to two weeks afterward. Results appear gradually over weeks to months. Cost ranges widely but typically falls between $300 and $1,000 per session, and multiple sessions are often needed.

Laser ablation and radiofrequency ablation use heat to seal the vein shut from inside. A catheter (thin tube) is inserted into the vein under ultrasound guidance, and energy is delivered as the catheter is withdrawn. These procedures take 30 to 60 minutes, require local anesthesia, and have high success rates—80 to 90 percent of treated veins remain closed after one year. Recovery is faster than surgery, and you can walk when ready. Compression stockings are worn for one to two weeks. Cost is typically $1,500 to $3,000 per vein, though insurance often covers these if the vein causes symptoms.

Endovenous mechanochemical ablation combines mechanical damage to the vein wall with a chemical agent. It is newer than laser or radiofrequency methods and may cause less pain during the procedure, though long-term outcome data is still being gathered. Cost is similar to laser or radiofrequency ablation.

Surgical options

Surgical removal, called vein stripping or ligation, is now used only when varicose veins are severe, affect large veins, or minimally invasive options have failed. The surgeon makes small incisions and removes or ties off the affected vein. The procedure is done under general or regional anesthesia and takes 1 to 2 hours. Recovery involves several weeks of restricted activity, and bruising and soreness are common. Complications like nerve damage or infection occur in a small percentage of cases. Cost ranges from $1,500 to $3,000, though insurance coverage depends on medical necessity.

Because minimally invasive procedures have lower complication rates and faster recovery, they are now the first-line surgical choice for most people. Vein stripping is reserved for cases where other options are not suitable.

Insurance coverage and cost considerations

Whether insurance covers varicose vein treatment depends on your plan and whether the procedure is deemed medically necessary. If the vein causes pain, swelling, skin changes, or complications, treatment is more likely to be covered. If the concern is purely cosmetic, you will likely pay out of pocket. Before scheduling any procedure, contact your insurance company and ask whether they cover the specific treatment your doctor recommends. You will need your doctor to document symptoms and medical reasoning in writing.

Medicare covers varicose vein treatment if specific criteria are met: the vein must cause symptoms, conservative treatment must have been tried first, and imaging must confirm the problem. Coverage rules vary by state and plan. Private insurance varies widely; some plans cover minimally invasive procedures at 70 to 80 percent after you meet your deductible, while others do not. Ask your doctor's office to submit a pre-authorization request to your insurer before the procedure so you know your out-of-pocket cost in advance.

Complications and when to seek urgent care

Varicose veins themselves rarely cause serious harm, but complications can occur. Deep vein thrombosis (a blood clot in a deep vein) is uncommon but serious and requires when ready medical attention. Signs include sudden severe swelling, warmth, redness, or pain in one leg. Superficial thrombophlebitis (a clot in a surface vein) causes a hard, tender, red cord along the vein and is less dangerous but still needs evaluation. Skin ulcers can develop near the ankle if circulation is severely compromised; these are slow to heal and prone to infection.

After any procedure, contact your doctor if you develop signs of infection (fever, increasing redness, pus), severe pain not relieved by over-the-counter medication, or signs of a blood clot. These are rare, but prompt attention prevents complications.

Frequently Asked Questions

Can varicose veins go away on their own?

No. Once a vein valve fails, it does not repair itself. However, symptoms often improve with self-care, and the veins may not worsen for years. Some people live with varicose veins their whole life without needing treatment.

Will varicose veins come back after treatment?

The treated vein usually stays closed, but new varicose veins can develop elsewhere because the underlying valve weakness is often genetic. Recurrence rates are roughly 10 to 15 percent within five years for minimally invasive procedures and higher for sclerotherapy. Compression stockings and movement after treatment may reduce recurrence risk.

Are varicose veins dangerous?

Most are not. They are a cosmetic or comfort concern for most people. Serious complications like blood clots are uncommon. However, if varicose veins cause skin changes, ulcers, or severe swelling, they warrant medical evaluation to rule out circulation problems.

Can I prevent varicose veins?

If family history is strong, prevention is difficult because genetics play a large role. However, staying active, maintaining a healthy weight, avoiding prolonged standing or sitting, and wearing compression stockings if you have risk factors may delay onset or slow progression.

How long does recovery take after a procedure?

Sclerotherapy and laser ablation allow you to return to normal activity the same day, though you must wear compression stockings for one to two weeks. Surgical removal requires several weeks of restricted activity and gradual return to normal. Your doctor will give you specific restrictions based on the procedure performed.
