Varicose veins can be eliminated through several proven methods, ranging from in-office procedures with success rates above 90% to lifestyle changes that reduce symptoms and slow progression. The right approach depends on whether your veins are causing symptoms like pain and swelling or are primarily a cosmetic concern, because that distinction affects both your treatment options and whether insurance will cover the cost.
Why Varicose Veins Form
Your leg veins contain one-way valves that push blood upward toward the heart. When those valves weaken or fail, blood flows backward and pools in the vein, stretching it outward into the bulging, rope-like appearance you see at the surface. This can happen because of inherited weakness in the vein wall, hormonal changes (especially during pregnancy), prolonged standing, or aging.
The pressure difference is significant. Standing venous pressure in your legs runs around 80 to 90 mmHg. When your calf muscles contract during walking, that pressure should drop by at least half. In legs with faulty valves, the pressure barely drops with exercise and snaps back to resting levels in under 20 seconds, keeping veins under constant strain. That sustained pressure is what drives the progressive bulging, heaviness, and skin changes many people experience over time.
Heat-Based Procedures: Laser and Radiofrequency Ablation
The most common way to permanently close a varicose vein is thermal ablation, performed in a doctor’s office under local anesthesia. A thin catheter is inserted into the damaged vein through a tiny skin puncture, then delivers either laser energy or radiofrequency waves to seal the vein shut. Your body reroutes blood through healthy veins automatically.
Both methods work extremely well. At one month, radiofrequency ablation closes the treated vein about 98.4% of the time, and laser ablation closes it about 98%. At one year, the rates dip slightly to around 93% for radiofrequency and 94% for laser. Radiofrequency tends to cause less post-procedure discomfort and nerve irritation, which is why some specialists prefer it for veins that run close to nerves, like those behind the knee. Long-term data shows radiofrequency may have a slight edge in preventing the vein from reopening at the three- and five-year marks.
Recovery is quick. You can return to normal activities within a few days. Aerobic exercise, including walking, running, and yoga, can typically resume four to five days after the procedure as long as you feel comfortable. Most people go back to work within a day or two.
Medical Adhesive (Vein Glue)
A newer option uses a medical-grade adhesive injected into the vein to seal it closed, without any heat. This eliminates the need for the multiple numbing injections along the vein that thermal ablation requires, and it carries virtually no risk of nerve injury. In a study following over 2,900 treated veins for up to 100 months, complications were rare. Only 0.9% of cases developed a minor lymphatic leak at the injection site. No nerve damage, blood clots, infections, or lasting skin reactions were reported.
The tradeoff is that vein glue is newer, so long-term data beyond eight years is still limited. Some insurers also consider it investigational and may not cover it.
Sclerotherapy for Smaller Veins
Sclerotherapy involves injecting a chemical solution directly into the vein, causing it to scar shut and eventually fade. It works best on spider veins and smaller varicose veins. The solution comes in two forms: liquid and foam. Foam is significantly more effective for larger veins because it displaces blood and makes better contact with the vein wall. In a controlled trial treating veins 4 to 8 mm in diameter, foam sclerotherapy had a 53% success rate at two years compared to just 12% for liquid.
Because of those numbers, foam sclerotherapy is often used as a complement to ablation rather than a standalone treatment for large varicose veins. It’s especially useful for mopping up visible branches after the main trunk vein has been sealed with heat or adhesive. Spider veins and small reticular veins respond well to liquid sclerotherapy alone, though multiple sessions are usually needed.
Ambulatory Phlebectomy
For bulging surface veins that are too large for sclerotherapy but don’t involve the deeper trunk veins, ambulatory phlebectomy removes them through tiny punctures in the skin. The punctures are so small they rarely need stitches and leave minimal scarring. This is often performed in the same visit as thermal ablation, targeting the visible bulges while ablation handles the underlying valve problem.
Compression Stockings: What They Do and Don’t Do
Compression stockings won’t make varicose veins disappear, but they can significantly reduce symptoms like aching, swelling, and heaviness. They work by applying graduated pressure to your legs, helping your calf muscles push blood upward more efficiently.
For varicose veins, you’ll generally want firm compression in the 20 to 30 mmHg range. Mild stockings (8 to 15 mmHg) help with minor fatigue but aren’t strong enough for established varicose veins. Extra firm stockings (30 to 40 mmHg) are reserved for severe swelling, skin changes, or post-surgical recovery and typically require a prescription.
Current clinical guidelines from the Society for Vascular Surgery recommend procedures over long-term compression for symptomatic patients who are good candidates for intervention. Compression is suggested as the primary approach only when a conservative strategy is preferred or when patients aren’t ready for a procedure.
Exercise and Calf Muscle Training
Your calf muscles act as a pump that squeezes blood upward through your leg veins with every step. Strengthening that pump improves venous return and can meaningfully reduce pain, swelling, and the feeling of heaviness.
A clinical trial comparing calf muscle training with compression therapy found large improvements in quality of life, venous refill time (a direct measure of how well blood flows back toward the heart), pain, swelling, and daily function. The training protocol included heel raises on both feet, single-leg heel raises, toe raises, ankle pumps while seated, mini-squats, and resistance band exercises for the calves and ankles. Patients started with low-resistance bands and gradually increased the difficulty over several weeks.
Walking is the simplest way to activate the calf pump throughout the day. If your job keeps you standing or sitting for long periods, periodic calf raises and ankle pumps can help keep blood moving.
Horse Chestnut Seed Extract
Horse chestnut seed extract is the most studied herbal supplement for venous insufficiency. A Cochrane review of multiple trials found it reduced leg volume by an average of about 32 ml compared to placebo and improved leg pain, swelling, and itching over treatment periods of two to sixteen weeks. The active compound works by reducing the permeability of small blood vessels, which helps prevent fluid from leaking into surrounding tissue.
The review found the extract performed comparably to compression stockings and another plant-based supplement (pine bark extract) for most symptoms. It’s available over the counter in capsule form, standardized to its active component. Raw horse chestnut seeds are toxic and should never be consumed.
What Insurance Requires Before Covering Treatment
If your varicose veins cause symptoms, insurance will likely cover treatment, but only after you’ve completed a three-month trial of conservative measures. Medicare’s coverage criteria are specific: you need to have tried exercise, periodic leg elevation, weight management, compression stockings, and avoiding prolonged immobility where appropriate.
After that three-month period, coverage requires at least one of the following: pain severe enough to limit activity or mobility, recurrent superficial vein inflammation, non-healing skin ulcers, bleeding from a varicose vein, skin discoloration from chronic blood pooling, or swelling that doesn’t respond to conservative care. Treatment of asymptomatic varicose veins is considered cosmetic and is not covered.
If your veins are purely a cosmetic concern (no pain, swelling, or skin changes), you can still pursue treatment, but expect to pay out of pocket. Sclerotherapy for spider veins almost always falls into this category. For veins that are asymptomatic and limited to small spider veins or reticular veins, guidelines recommend against routine ultrasound evaluation, since testing could lead to unnecessary procedures on veins that don’t need treatment.
