Many patients in Hendersonville, TN notice visible changes in their legs and wonder what they are looking at. Are those small red lines spider veins? Are the larger, twisted cords varicose veins? Does the difference matter for treatment? Yes, it does. Knowing which condition you have helps you get the right care.
What Are Spider Veins?
Spider veins are small, damaged blood vessels that appear close to the surface of the skin. They are usually red, blue, or purple and tend to form a web-like pattern — which is where they get their name. They are typically flat or barely raised and measure just one to three millimeters across.
Spider veins most often appear on the legs, ankles, and face. They rarely cause serious symptoms, though some patients notice mild burning, itching, or tenderness. For many patients, the main concern is how they look.
Spider veins are very common. According to the National Heart, Lung, and Blood Institute, up to forty percent of adults have some form of visible vein condition.
What Are Varicose Veins?
Varicose veins are larger, deeper veins that have become swollen, twisted, and raised above the surface of the skin. They are typically blue or dark purple and can look like thick cords running along the legs. They are significantly larger than spider veins, often measuring three millimeters or more across.
Unlike spider veins, varicose veins are more than a cosmetic concern. They develop when the one-way valves inside the veins fail — a condition called venous reflux (when blood flows backward and pools instead of moving toward the heart). This pooling causes the vein to stretch and become enlarged and visible.
Common symptoms of varicose veins include:
- Aching, throbbing, or heaviness in the legs
- Swelling in the lower legs and ankles
- Cramping or restlessness, especially at night
- Skin changes near the affected vein, including discoloration or hardening
- Itching or irritation along the vein
Left untreated, varicose veins can worsen over time. In some cases, chronic venous insufficiency can develop and lead to skin changes or ulcers. Early evaluation and treatment matter.
Spider Veins vs Varicose Veins: A Side-by-Side Comparison
Understanding the key differences makes it easier to identify what you may be experiencing:
Size: Spider veins — small, one to three millimeters | Varicose veins — larger, three millimeters or more, visibly raised
Appearance: Spider veins — thin, web-like patterns in red, blue, or purple | Varicose veins — thick, twisted, rope-like cords in blue or dark purple
Location: Spider veins — close to the skin surface, flat or slightly raised | Varicose veins — deeper and clearly raised above the skin
Symptoms: Spider veins — usually painless or mildly uncomfortable | Varicose veins — commonly cause aching, swelling, heaviness, and cramping
Complication risk: Spider veins — primarily cosmetic, rarely cause complications | Varicose veins — higher risk, including skin changes and chronic venous insufficiency
Cause: Spider veins — weakened superficial vein valves | Varicose veins — more significant valve dysfunction in the deeper venous system
What Causes Both Conditions?
Both spider veins and varicose veins result from weakened valves inside the veins. These valves keep blood moving in one direction — toward the heart. When they weaken, blood flows backward and pools. Over time, this stretches the vein walls.
Risk factors for both conditions include:
- Family history — vein conditions have a strong genetic component
- Pregnancy — increased blood volume and hormonal changes put extra pressure on veins
- Prolonged sitting or standing — common in many occupations
- Being overweight — excess weight increases pressure on the leg veins
- Age — valve function naturally decreases over time
- Female sex — up to seventy-five percent of patients diagnosed with varicose veins are women
Treatment Options Available in Hendersonville, TN
The Vein Guys in Hendersonville, TN offer several effective, minimally invasive treatments for both spider veins and varicose veins. All procedures are performed by board-certified physicians in a comfortable in-office setting.
For spider veins, Sclerotherapy is a widely used treatment. A sclerosant solution is injected directly into the affected vein through a fine needle. The vein collapses and fades gradually over four to six weeks. Most sessions take thirty to sixty minutes. Multiple sessions may be recommended depending on the extent of the condition.
For varicose veins, Venefit™ (radiofrequency ablation) is an effective option. Controlled radiofrequency energy is applied to the inside of the diseased vein, causing it to close. Blood is naturally redirected to healthier vessels. The procedure typically takes about fifteen minutes and requires no general anesthesia. Patients can usually return to normal activities shortly afterward.
VenaSeal™ is another option for patients with varicose veins. It uses a medical adhesive to seal the diseased vein — no heat and no large-volume anesthesia injection required. This makes it a comfortable choice for patients who prefer to avoid thermal treatments.

Frequently Asked Questions
What is the main difference between spider veins and varicose veins?
Spider veins are small, web-like vessels near the surface of the skin, usually one to three millimeters wide. They are primarily cosmetic. Varicose veins are larger, raised, twisted veins that result from significant valve dysfunction inside the vein. Varicose veins commonly cause physical symptoms including aching, swelling, and cramping, and may lead to complications if left untreated.
Can spider veins turn into varicose veins?
Spider veins and varicose veins are related but separate conditions. They both result from weakened vein valves, but they tend to develop in different parts of the venous system. Spider veins do not typically transform into varicose veins. However, both can worsen over time without evaluation and treatment.
Is treatment for spider veins and varicose veins covered by insurance?
Coverage varies depending on the insurance plan and the nature of the condition. Varicose vein treatment is more likely to be covered when there are documented medical symptoms such as pain, swelling, or skin changes. Spider vein treatment is often considered cosmetic and may not be covered. The Vein Guys’ team can help patients understand their coverage and treatment options during a consultation.
Are varicose veins dangerous?
Varicose veins are not always dangerous, but they can become a more serious health concern over time. Chronic venous insufficiency, skin changes, and in rare cases, superficial blood clots may develop if the condition is left untreated. If you notice skin changes near a varicose vein or experience significant swelling or discomfort, a professional evaluation is important.
How do I know which treatment is right for me?
The appropriate treatment depends on the type, size, and location of the affected veins, as well as your overall health and medical history. A thorough evaluation — including a vascular ultrasound performed by a Certified Registered Vascular Technologist — is the foundation of any treatment plan at The Vein Guys. There is no one-size-fits-all approach.
