about vein disease

What is vein disease?

Vein disease, often called chronic venous insufficiency, happens when the tiny valves inside your leg veins weaken or fail. Instead of flowing up toward the heart, blood pools in the legs, raising pressure in the veins.
Over time, that pressure leads to varicose and spider veins, swelling, aching, and skin changes. The good news: vein disease is highly treatable, and most patients find lasting relief without surgery.
How healthy veins work
Leg veins rely on one-way valves and your calf muscles to push blood upward against gravity. When valves leak, blood flows backward (reflux) and collects below — the root cause of most vein symptoms.
CAUSES & RISK FACTORS

What causes vein disease?

Vein disease develops when leg-vein valves weaken. Several factors raise your risk of that happening.

Family History

If a parent or sibling has varicose veins, you're far more likely to develop them too.

Prolonged standing or sitting

Jobs that keep you on your feet — or seated —
all day let blood pool in the legs.

Pregnancy & hormones

Increased blood volume and hormonal shifts
during pregnancy strain leg veins.

Age

Vein valves naturally wear down over time, so
risk climbs as you get older.

Obesity or high BMI

Extra body weight adds pressure on the veins
in your legs and pelvis.

Inactivity

A sedentary lifestyle weakens the calf-muscle pump that moves blood upward.

SYMPTOMS

What are the symptoms 
of vein disease?

Vein symptoms range from cosmetic to debilitating. Many people dismiss tired, heavy legs as part of aging — but these are often early signs of treatable venous insufficiency. Left untreated, symptoms tend to worsen and can progress to skin damage and leg ulcers.
  • Bulging or twisted veins
  • Leg aching or throbbing
  • Swelling in legs or ankles
  • Heaviness or fatigue
  • Night cramps
  • Restless legs
  • Itching or burning
  • Skin discoloration
  • Slow-healing leg ulcers
  • Spider veins
What we treat

Vein & vascular conditions we treat

From cosmetic spider veins to advanced circulation problems, our specialists treat the full range of venous and arterial conditions.

Varicose veins

Enlarged, twisted veins that often cause aching, heaviness, or swelling in the legs.

Spider veins

Small, visible veins on the surface of the skin
that often appear red, blue, or purple.

Chronic venous insufficiency (CVI)

Weakened leg vein valves impair blood flow to
the heart, causing swelling and skin changes.

Deep vein thrombosis (DVT)

A serious condition where blood clots in the deep leg veins can cause life-threatening complications.

Leg discoloration

Skin darkening or color changes caused by poor circulation and prolonged venous disease.

Leg pain

Aching, burning, or throbbing sensations in the
legs, often linked to underlying vein dysfunction.

Leg ulcers

Open sores near the ankles or calves that are slow to heal due to poor blood flow and venous disease.

Pelvic congestion syndrome

Enlarged pelvic veins that cause chronic pelvic
pain, especially in women who have had children.

Restless leg syndrome

An uncontrollable urge to move the legs that is sometimes related to underlying venous conditions.

TREATMENT

Minimally invasive vein treatment: relief without surgery

Modern vein care is image-guided and done right in our office. Using ultrasound, our doctors close the faulty vein so blood reroutes to healthy ones. No hospital stay, no large incision, no vein stripping.
How embolization works
  1. A tiny catheter is guided into the faulty vein using ultrasound — through a pinhole, with local numbing only.
  2. The vein is sealed shut with radiofrequency heat or medical adhesive.
  3. Blood naturally reroutes to healthy veins, and symptoms fade as pressure drops.
Depending on your veins, we may use endovenous radiofrequency ablation (RFA), VenaSeal adhesive, sclerotherapy, Varithena foam, or ambulatory phlebectomy. Most procedures take 30–60 minutes, and you can walk out and resume light activity the same day.

Outpatient, same-day

No hospital stay. Most patients go home within hours.

No surgical incision

A single pinhole — no vein stripping, no general anesthesia.

Walk in, walk out

Most patients return to normal activity the very next day.

Covered by most insurance

Medically necessary vein treatment is covered by most major plans.

What is vein disease (chronic venous insufficiency)?

Chronic venous insufficiency (CVI) occurs when the valves in your leg veins weaken and allow blood to flow backward and pool in the legs. This raises pressure in the veins and is the root cause of most varicose veins, spider veins, leg swelling, and skin changes. It's very common and highly treatable, often without surgery.

Are varicose veins dangerous, or just cosmetic?

While some people only dislike how varicose veins look, they are often a sign of underlying venous insufficiency. Left untreated, they can lead to worsening pain, swelling, skin discoloration, bleeding, blood clots, and slow-healing leg ulcers. An ultrasound evaluation tells us whether treatment is medically necessary.

How are vein problems diagnosed?

Diagnosis starts with a physical exam and your symptom history, followed by a painless duplex ultrasound. The ultrasound shows blood flow in real time and pinpoints exactly which veins have faulty valves, allowing us to build a precise, personalized treatment plan.

What are the treatment options for varicose veins?

Most patients are treated without surgery. The main options are:

  • Endovenous radiofrequency ablation (RFA) — heat seals the faulty vein closed.
  • VenaSeal — a medical adhesive closes the vein, no heat needed.
  • Sclerotherapy & Varithena — injections that collapse spider and smaller veins.
  • Ambulatory phlebectomy — tiny removal of surface veins through pinholes.

Is vein treatment painful, and what's the recovery like?

Procedures are done under local numbing, so discomfort is minimal — most patients feel only a small pinch. There's no hospital stay and little to no downtime. You'll wear compression stockings for a short period and can usually walk immediately and return to normal activities the next day.

Does insurance cover vein treatment?

Yes. When vein treatment is medically necessary — meaning you have symptoms like pain, swelling, or skin changes — it's covered by most major insurance plans and Medicare. Our team verifies your benefits in advance and handles the documentation. Purely cosmetic spider-vein treatment is typically out of pocket.

Will my varicose veins come back after treatment?

A vein that's been properly sealed or removed will not return. However, because vein disease is progressive, new veins can develop over time. Wearing compression stockings, staying active, and attending follow-up visits greatly reduces the chance of new problem veins and keeps your results lasting.

How long does a vein procedure take?

Most minimally invasive vein procedures take about 30 to 60 minutes and are performed right in our office. You're awake the whole time, and you can typically drive yourself home and resume light activity the same day.

When should I see a vein specialist?

See a specialist if you have bulging or painful veins, persistent leg swelling, heaviness or aching that worsens through the day, restless legs at night, skin discoloration around the ankles, or any open sore that won't heal. Early evaluation prevents the condition from progressing.
