Why Varicose Veins and Spider Veins Cause Pain

When most people think of varicose veins or spider veins, they imagine bulging or web-like veins that change the appearance of the legs. While the cosmetic impact is real, what many don’t realize is that these veins can also cause significant discomfort, heaviness, and even sharp pain. At Sheen Vein (Aesthetics and Functional Medicine) here in St. Louis, we see patients every day who are surprised to learn that the pain in their legs is directly connected to poor vein circulation.

Let’s explore why varicose veins and spider veins cause pain and what you can do about it.

Understanding Varicose and Spider Veins

Healthy veins have one-way valves that keep blood moving back toward the heart. In varicose veins, these valves weaken or fail, causing blood to pool in the leg veins. The pooling stretches the vein walls, making them bulge and twist under the skin. Spider veins, while smaller and closer to the surface, result from similar valve dysfunction and increased pressure in the tiny blood vessels.

Although spider veins are often thought of as purely cosmetic, both conditions can contribute to symptoms that impact daily comfort and mobility.

Why Do They Hurt?

1. Pressure Build-Up in the Veins

When blood pools in varicose or spider veins, it creates excess venous pressure. This pressure stretches the delicate vein walls and surrounding tissues, which can cause aching, throbbing, and a heavy feeling in the legs—especially after long periods of standing or sitting.

2. Inflammation of the Vein Walls

Chronic venous insufficiency leads to inflammation. Inflammation irritates the nerves around the vein and can trigger burning, itching, or tenderness. Some patients describe it as a “deep soreness” that doesn’t go away with rest.

3. Poor Oxygen Delivery

When veins don’t efficiently return blood to the heart, oxygen delivery to the tissues of the legs suffers. That lack of oxygenation can lead to cramps, restless legs at night, and fatigue in the muscles.

4. Nerve Irritation

Swollen varicose veins can compress nearby nerves, leading to tingling, numbness, or sharp shooting pains. This explains why some patients experience discomfort out of proportion to the visible size of their veins.

5. Complications That Cause Pain

Sometimes, pain comes from complications of untreated varicose veins, such as superficial blood clots (phlebitis), skin ulcers, or bleeding from fragile vein walls. These conditions can become serious if ignored.

Common Symptoms Patients Report

At Sheen Vein, we often hear our St. Louis patients describe:

  • Heavy, aching legs by the end of the day
  • Burning or itching around visible veins
  • Leg cramps or throbbing at night
  • Swelling in the ankles or calves
  • Sharp pain after prolonged standing
  • Restlessness that interrupts sleep

If these symptoms sound familiar, they may be more than a nuisance—they may signal underlying venous insufficiency that deserves attention.

Why Ignoring Vein Pain Is Risky

Many people delay seeking treatment because they assume varicose or spider veins are “just cosmetic.” Unfortunately, untreated venous disease tends to progress. Over time, pain worsens, swelling increases, and skin changes (such as discoloration, eczema-like patches, or even ulcers) may develop.

By addressing the problem early, patients not only relieve pain but also reduce the risk of long-term complications.

Relief and Treatment Options

The good news is that modern vein treatments are safe, effective, and minimally invasive. At Sheen Vein (Aesthetics and Functional Medicine), we offer:

  • Endovenous Laser Therapy (EVLT): A quick, office-based treatment that closes diseased veins from the inside.
  • Ultrasound-Guided Sclerotherapy: Injection therapy to treat hidden or deeper varicose veins.
  • Foam Sclerotherapy (Varithena®): An advanced option for larger, tortuous veins.
  • Cosmetic Sclerotherapy: For visible spider veins that cause discomfort or cosmetic concerns.

These treatments restore healthy blood flow, reduce pressure in the veins, and relieve pain while improving appearance.

If you live in the St. Louis area and are experiencing pain from varicose veins or spider veins, you don’t have to suffer in silence. What may feel like a cosmetic issue is often a sign of a deeper circulation problem that deserves medical evaluation.

Varicose veins and spider veins are not just cosmetic nuisances. They can cause real, daily pain due to venous pressure, inflammation, and impaired circulation. Fortunately, effective treatments exist that can relieve discomfort and prevent long-term complications.
