Varicose Veins and Skin Discoloration: What the Color Changes Mean

Skin discoloration around the ankles and lower legs is a common concern for patients with varicose veins. Many people notice their skin becoming darker, reddish, or even purplish over time and assume it is simply part of aging. In reality, these color changes are often a sign of underlying venous disease and should not be ignored.

At the Vascular Center and Vein Clinic of Southern Indiana, board-certified vascular surgeon Dr. Ricardo Vasquez has over 20 years of experience diagnosing and treating varicose veins, venous insufficiency, and related skin changes. His office includes a fully accredited vascular ultrasound lab, allowing for immediate, in-office evaluation. Dr. Vasquez and Monroe Hospital were recognized as a Top 50 Vascular Surgery Hospital in the Nation by Healthgrades in 2024—the only hospital in Indiana with this distinction.

Why Varicose Veins Cause Skin Discoloration

Varicose veins develop when the valves in the veins stop working properly, allowing blood to pool in the lower legs. This increases pressure within the veins and surrounding tissues. Over time, small blood vessels begin to leak fluid and red blood cells into the skin.

As these red blood cells break down, they leave behind iron deposits, which cause the skin to darken. This process is known as hemosiderin staining and is one of the earliest visible signs of chronic venous insufficiency.

What Different Colors Can Mean

Not all skin discoloration looks the same, and the color can provide important clues about what is happening beneath the surface.

A reddish or inflamed appearance may indicate venous stasis dermatitis, a condition caused by chronic swelling and irritation. Patients often experience itching, dryness, or sensitivity in the affected area.

Brown or dark discoloration around the ankles is typically a sign of long-standing venous insufficiency. This pigmentation tends to worsen over time and does not resolve without treatment of the underlying vein problem.

In more advanced cases, the skin may appear purplish, thickened, or firm. These changes suggest ongoing inflammation and damage to the skin and underlying tissue, increasing the risk of breakdown and ulcer formation.

Why These Changes Should Not Be Ignored

Skin discoloration is not just a cosmetic issue. It is often an early warning sign that venous pressure is affecting the skin and that the condition is progressing.

Without treatment, patients may develop additional complications such as swelling, skin hardening (lipodermatosclerosis), recurrent rashes, or venous ulcers, which are open wounds that can be difficult to heal.

Addressing the condition early can prevent these complications and improve overall skin health.

The Importance of Early Evaluation

The most effective way to evaluate varicose veins and skin discoloration is through vascular ultrasound, which assesses blood flow and valve function. At Dr. Vasquez’s office, this testing is performed on-site in a fully accredited vascular lab, allowing for immediate diagnosis and treatment planning.

Patients do not need a referral and can schedule directly, avoiding hospital delays and additional costs.

Treatment Can Improve Skin Health

When venous insufficiency is treated, pressure in the legs decreases, which can help reduce inflammation and prevent further skin changes. Minimally invasive, in-office procedures can improve circulation and stop the progression of discoloration.

While some pigmentation changes may take time to improve, early treatment significantly reduces the risk of worsening skin damage.

When to Schedule an Appointment

If you notice darkening, redness, or other skin changes around your ankles or lower legs—especially if you also have varicose veins—it is important to seek evaluation.
