Lymphedema

The hidden cause of persistent leg swelling — and how we help manage it.

What Is Lymphedema?

Lymphedema is a condition where the body’s lymphatic system becomes impaired, leading to chronic leg lymphedema and swelling.

The lymphatic system helps drain excess fluid from tissues and return it to the bloodstream. When this system becomes damaged, overwhelmed, or blocked, fluid builds up in the tissue, causing swelling that doesn’t easily go away.

Common Signs of Lymphedema

Persistent leg or ankle swelling (often worse at the end of the day)
Swelling that doesn’t fully resolve with leg elevation
Heaviness, tightness, or discomfort in the legs
Thickened, firmer skin over time
Skin dimpling, folds, or “woody” texture in advanced cases

What Causes Lymphedema?

Primary Lymphedema:

A rare genetic or developmental condition where the lymphatic system is underdeveloped.

Secondary Lymphedema:

Far more common — occurs when the lymphatic system is damaged due to:
  ✔️ Chronic venous insufficiency (CVI)
  ✔️ Vein disease left untreated for too long
  ✔️ Surgery, trauma, infection, or cancer treatments (such as lymph node removal)

Lymphedema frequently develops after years of unmanaged vein disease.

Is It the Same as Vein Disease?

No — but it is often closely related.

Many patients with chronic venous insufficiency (CVI) or untreated vein disease develop combined venous and lymphatic swelling. This is sometimes called phlebolymphedema.

In these cases, the failing veins create excess pressure in the leg, overloading the lymphatic system over time.

When vein disease is part of the problem, treating it can significantly reduce swelling and improve lymphatic function.

How We Help Manage Lymphedema

Management starts with a thorough evaluation to determine whether your swelling is due to vein disease, lymphatic dysfunction, or both.

✔️ If vein disease is present, we treat it first. Correcting the venous insufficiency reduces pressure in the legs and often results in significant improvement in swelling and lymphatic function.

For true or residual lymphedema, our approach includes:
✔️ Pneumatic compression devices (at-home pump therapy) — organized through our clinic for qualifying patients
✔️ Compression garments — properly fitted for your needs
✔️ Long-term vein health management
✔️ Education on skin care, swelling control techniques, and lifestyle strategies to maintain leg health

Is Treatment Covered by Insurance?

Yes. Pneumatic compression devices and vein treatments are typically covered when medically necessary and properly documented.
