What Causes Leg Discoloration?

If your legs are discolored, you may have a problem with your veins or overall blood circulation. So, if you look down and see red, brown, purple, blue, or black, it’s time to see the vein specialists at Precision Vascular in Arlington, Dallas, Mesquite, and McKinney, Texas.

What causes leg discoloration?

Leg discoloration may be caused by many different health conditions. Here’s a look at some of the more common ones and what to watch for:

Chronic venous insufficiency

Chronic venous insufficiency occurs when the valves in your veins don’t close properly, allowing blood to pool. As a result, your leg may swell and your skin may change color. You may also have a condition called venous stasis dermatitis with red, yellow, or brown itchy or tender skin. Your legs may also ache, throb, or cramp. Treatment includes elevating your legs and wearing compression stockings. 

This condition could also lead to varicose veins, which are twisted, enlarged veins that seem to pop out of the skin, or spider veins, which appear like broken blood vessels under the skin. 

Deep vein thrombosis

Deep vein thrombosis, or DVT as it’s also known, occurs when a blood clot forms in the veins deep in your legs or other areas. As the blood clot blocks blood flow, you may feel pain, or your leg may swell, and it may look blue or red in color. This condition becomes life-threatening when a blood clot breaks free and travels to your brain, heart, or lung. We can help by prescribing blood thinners or clot busters, or by performing a minimally invasive procedure to remove the blood clot. But sometimes, a trip to the emergency room is necessary.


It’s true: People with diabetes must keep an extra eye on their legs because they have poor circulation. Slow-healing sores may develop, and they’re also prone to infection. People with diabetes may also have leg discoloration because of the following conditions:


If your legs are discolored, there’s a good chance it’s from a problem with your veins. Sometimes, it could be something else, like a bug bite or hives. The only way to know for sure is to make an appointment with one of our vein specialists at Precision Vascular. They’ll provide a comprehensive exam and may order blood tests, ultrasounds, or other diagnostic tests to get the full picture.
