Should I Be Concerned About Leg Discoloration?

Have you noticed differences in the skin color of your legs? Maybe your ankles look darker than usual, or you’ve spotted red, purple, or even brown patches on your skin. While leg discoloration might not always be severe, it can signal an underlying health issue, especially when paired with leg pain, swelling, or visible veins.
At Vascular Surgery Associates, we want to help you understand what leg discoloration means and when to schedule a diagnostic consultation with a vascular specialist. Some color changes, like mild bruises, aren’t a big deal. But you should take leg discoloration seriously if you also notice:
- Leg or ankle discoloration that doesn’t go away
- Swelling in one or both legs
- New or worsening leg pain
- Skin that feels cool or changes texture
- Sores that don’t heal
- Sudden redness or warmth in the leg
These may be signs of peripheral vascular disease, affecting how blood moves through your veins and arteries.
Causes of leg discoloration
Leg discoloration can happen for many reasons. Some are harmless, but others point to conditions that need treatment. Common causes include:
Spider veins and varicose veins
These visible veins can make the skin look blue, purple, or reddish. Varicose veins may also cause aching, leg swelling, and a heavy feeling in the legs.
Chronic venous insufficiency (CVI)
CVI or venous reflux happens when blood has trouble flowing back up the legs to the heart. It can lead to varicose veins, ankle discoloration, swelling, skin thickening, ulcers (slow-healing sores), and stasis dermatitis.
Lymphedema
Lymphedema occurs when your lymphatic system doesn’t drain fluid properly, causing swelling and skin changes in the legs.
Arterial disease
When arteries narrow due to plaque buildup (arterial blockages), blood flow is limited to your legs, which can cause pale or bluish skin, cold feet, and claudication (pain when walking).
Deep vein thrombosis (DVT)
A blood clot deep in your leg can cause sudden swelling, redness, and discoloration. DVT needs immediate medical attention due to the risk of a potentially life-threatening pulmonary embolism.
At Vascular Surgery Associates, we start with a careful exam and diagnostic consultation to understand your symptoms. We may recommend a vascular ultrasound — a painless test with sound waves to check your blood flow.
Treating leg discoloration
The good news is that we can effectively treat many causes of leg discoloration. Depending on the diagnosis, we may suggest:
Lifestyle changes
Exercising regularly, elevating your legs when seated, and wearing compression stockings can help with vein-related issues.
Sclerotherapy
Sclerotherapy is a simple injection that closes off small varicose and spider veins, helping improve appearance and reduce discomfort.
Varithena(™) microfoam vein treatment
Varithena is a gentle foam injected into varicose veins to close them off.
VenaSeal(™)
VenaSeal is a medical adhesive used to seal faulty veins and improve circulation.
ClosureFast(™) radiofrequency ablation
ClosureFast is a minimally invasive procedure using heat to close damaged veins.
Peripheral artery angioplasty
Angioplasty is a procedure to open up narrowed arteries and improve blood flow in patients with arterial disease.
Vascular surgery
Surgery may be necessary to repair or bypass blocked blood vessels in more serious cases.
If your leg discoloration is due to lymphedema or deep vein thrombosis, we guide you through other specialized treatments to reduce swelling, dissolve clots, and protect your long-term health.
Why early care matters
Ignoring leg discoloration can lead to big problems down the line. The skin can break down without proper blood flow and form painful ulcers. Blood clots can find their way to the lungs and cause potentially deadly pulmonary embolisms. You should take symptoms like leg swelling and skin discoloration seriously.
At Vascular Surgery Associates, we believe in catching problems early to optimize patient outcomes. Whether dealing with varicose veins or more complex vascular conditions, we’re here to help you feel better and live healthier.
