Visible leg veins, whether thin spider veins or bulging varicose veins, can be treated with a range of procedures that close or remove the affected vessels. The right approach depends on the size and type of vein, whether it’s causing symptoms, and what you’re willing to spend. Small spider veins often respond to a single in-office injection, while larger varicose veins typically need a heat-based or adhesive-based procedure to shut them down permanently.
Spider Veins vs. Varicose Veins
These two types of visible veins look different, feel different, and require different treatments. Spider veins are less than 1 millimeter wide. They appear as fine, wispy lines near the skin’s surface, often blue or red, and form when tiny blood vessels like capillaries are damaged. Most spider veins cause no symptoms at all, though some people notice mild burning or itching.
Varicose veins are wider than 3 millimeters and look like lumpy, ropey bulges under the skin. They develop when one-way valves inside the veins stop working properly, allowing blood to pool and stretch the vessel wall. Unlike spider veins, varicose veins frequently cause pain, swelling, itching, and in advanced cases, skin ulcers near the ankle. This distinction matters because insurance will almost never cover spider vein treatment (it’s considered cosmetic), but it often covers varicose vein procedures when symptoms are documented.
What You Can Do at Home
No home remedy will make visible veins disappear, but several strategies can slow their progression and reduce discomfort. Compression stockings are the single most effective non-procedural option. They work by applying graduated pressure to your legs, helping blood move upward instead of pooling in damaged veins. For mild symptoms or prevention, stockings in the 15 to 20 mmHg range are a good starting point. If you have moderate to severe swelling or pain, medical-grade stockings at 30 to 40 mmHg provide stronger support, though these are best fitted with guidance from a provider.
Regular exercise, periodic leg elevation, weight management, and avoiding long stretches of standing or sitting all help reduce venous pressure. These aren’t just general wellness tips. Medicare and most private insurers require a documented three-month trial of conservative measures like these before they’ll approve a procedure for varicose veins.
Horse Chestnut Extract
One supplement with actual clinical evidence behind it is horse chestnut seed extract. Its active compound reduces fluid leaking from damaged capillaries. In placebo-controlled trials, daily doses of 100 to 150 mg of the active component reduced lower leg volume, decreased calf and ankle circumference, and cut the rate of fluid filtration through capillary walls by 22 percent. Measurable improvements showed up within two weeks. It won’t eliminate visible veins, but it can meaningfully reduce the swelling and heaviness that come with them.
Sclerotherapy for Spider Veins
Sclerotherapy is the standard treatment for spider veins and small varicose veins. A provider injects a chemical solution directly into the vein, which damages the inner lining and causes the vessel to seal shut. Your body gradually absorbs the closed vein over the following weeks, and blood reroutes through healthier vessels nearby.
The procedure takes 15 to 30 minutes, requires no anesthesia, and you can walk out of the office afterward. Most people need more than one session to fully clear a cluster of spider veins. Treated veins typically fade over three to six weeks, though some take longer. The average cost for spider vein sclerotherapy is around $428 per session.
Heat-Based Procedures for Varicose Veins
For larger varicose veins, the most common approach is endovenous thermal ablation, which uses either laser energy or radiofrequency energy delivered through a thin catheter inserted into the vein. Both methods heat the vein wall from the inside, causing it to collapse and seal. A comparative analysis in the Journal of Vascular Surgery found an overall closure rate of 96.6 percent, with no significant difference between laser and radiofrequency.
These procedures are performed under local anesthesia in an outpatient setting. You’ll typically return to a desk job within a few days, though physically demanding work may require a longer break. Strenuous exercise is off limits until your provider clears you, and you should avoid flying for two weeks after the procedure. Compression stockings are usually worn for one to two weeks during recovery.
Endovenous laser ablation typically costs between $1,000 and $3,000 per leg. If you meet the medical necessity criteria (documented symptoms, failed conservative therapy, appropriate vein anatomy), insurance often covers a significant portion.
Adhesive and Mechanical Options
Newer techniques avoid heat entirely. VenaSeal uses a medical-grade adhesive injected into the vein, which glues the walls together. Because there’s no heat involved, it doesn’t require the numbing injections along the vein that thermal procedures do. In a network meta-analysis comparing it to other treatments, VenaSeal ranked first for reduction in postoperative pain and had the lowest rate of adverse events.
The trade-off is cost. VenaSeal runs between $5,000 and $13,000, and insurance coverage for it is less predictable than for traditional thermal ablation. For people who are especially anxious about needles or want the least painful recovery possible, it may be worth the premium.
What Insurance Requires
Insurance companies, including Medicare, follow specific criteria before approving varicose vein procedures. You’ll need to show that you’ve tried conservative therapy (compression, exercise, leg elevation, weight management) for at least three months without adequate relief. You also need at least one documented symptom: pain severe enough to limit mobility, recurrent vein inflammation, non-healing ulcers, bleeding from a varicosity, skin changes from chronic swelling, or persistent edema that doesn’t respond to conservative treatment.
Your provider will order a venous ultrasound to map the problem veins and confirm that blood is flowing backward through faulty valves. For thermal ablation to be approved, the vein must fall within certain size limits (generally under 20 mm for radiofrequency, under 30 mm for laser), and the vein can’t be too twisted for a catheter to pass through.
Spider vein treatment is almost always out of pocket. The only exception is when spider veins are actively bleeding, which is rare.
Choosing the Right Treatment
Your decision comes down to what kind of veins you have and what’s driving your desire to treat them. For cosmetic spider veins with no symptoms, sclerotherapy at a few hundred dollars per session is straightforward and effective. For symptomatic varicose veins, thermal ablation offers a 96-plus percent success rate at a moderate cost, especially if insurance covers part of it. VenaSeal provides the gentlest recovery experience but at a significantly higher price point.
Whichever route you choose, treated veins don’t come back. New veins can develop over time, though, because the underlying tendency toward weak valves doesn’t change. Maintaining a healthy weight, staying active, wearing compression stockings during long periods of standing, and elevating your legs when you can all help delay the formation of new visible veins.
