Bulging bluish to purple veins may not be the only skin condition you experience if you have varicose veins. You may also have a skin condition in the form of eczema known as varicose eczema or venous stasis dermatitis.

Read on to find out more about the symptoms of varicose eczema, what causes it, and what you can do if you have it.

Varicose eczema is a skin condition that causes skin changes in your lower legs when you have varicose veins.

The condition is also referred to as:

Along with itchy varicose veins, early varicose eczema symptoms may include:

  • dry, scaly rash
  • red or discolored, inflamed, and slightly shiny skin
  • hyperpigmentation or discolored skin (usually a rust or brown color)
  • aching legs
  • ankle swelling that tends to get better when you sleep but swells when you wake up
  • warm feeling in your legs, although your skin remains cool when you touch it

Some areas of your skin may break down over time and form painful varicose leg ulcers or open sores, most often near your ankle. A 2017 research review showed that about 500,000 people in the United States have these venous ulcers.

Other severe symptoms include:

  • crusty or cracked skin
  • weeping eczema or oozing, fluid-filled blisters on your skin
  • swelling in your legs that persists

You may also experience a condition called lipodermatosclerosis as your varicose eczema worsens. This happens as subcutaneous fat, the fat under your skin, grows inflamed causing your skin to become:

  • hard and thick
  • tender and painful
  • red to red-brown or violet-brown colored

Varicose veins occur when the one-way valves in the veins in your legs grow weak. This causes venous insufficiency or improper blood flow from your limbs upward to your heart.

Blood then pools in the veins in your legs and leaks into your body tissues. Your immune system reacts by making your skin inflamed and causing eczema symptoms to appear.

Varicose eczema often appears in the advanced stages of chronic venous insufficiency (CVI). About 2 to 6 million people in the United States have advanced forms of CVI, according to a 2017 research review.

Along with having CVI, your dermatologist will look for hallmark skin changes and ask about your symptoms.

These are often enough to diagnose varicose eczema, but other tests may be needed to confirm findings or exclude other types of skin conditions.

These tests may include:

  • Skin patch test. In this test, your doctor will expose your skin to different potential allergens your skin may react to. This test helps determine if your eczema is caused by allergic contact dermatitis.
  • Doppler ultrasound. This imaging test uses sound waves to create pictures that help doctors measure blood flow through your limbs.
  • Ankle brachial index test. This test measures blood flow to your legs and looks for areas where blood flow is fully or partly blocked.
  • Cardiac tests. There are several tests like electrocardiograms (ECG or EKG), chest X-rays, echocardiograms, and others that measure your heart function.
  • Artery studies. These tests measure blood flow in your arteries and are used to check for conditions that may contribute to your varicose eczema.

The American Academy of Dermatology Association (AADA) makes these suggestions that may help lower your risk and reduce symptoms:

Take breaks from sitting or standing

If you sit or stand for more than an hour, take breaks from doing so by walking briskly for at least 10 minutes to boost blood flow.

Work out

Working out helps enhance blood flow and strengthen your leg muscles.

Avoid injury at or near varicose veins

Try to protect affected areas of your skin from getting injured as these can lead to open sores.

Do not scratch these areas or touch things that can further inflame your skin such as:

  • harsh cleaning products
  • grass
  • pet hair
  • perfumes
  • skin care products with fragrance

Wear cotton clothing that fits loosely

Rough fabrics such as wool and rayon can chafe your skin while tight clothes can hamper blood flow and rub against your skin.

Maintain a moderate weight

Try to get to and stay at a moderate weight. This helps ease swelling and pressure on your veins. It also helps support your total health and lower your risk of other health conditions related to varicose eczema.

Hydrate well

Make sure you get enough fluids each day by drinking healthy fluids such as water or eating water-rich fruits and vegetables. This can improve blood flow and ease swelling.

Watch your salt intake

Try to limit your daily salt intake as having too much of it can hamper blood flow.

Varicose eczema occurs most often in middle-aged and older adults, occurring in about 20 percent of people who are more than 70 years old. Older age along with having varicose veins increases your risk of developing varicose eczema.

Living with overweight or obesity or pregnancy can also raise your risk of developing varicose eczema due to your veins’ added pressure.

Current or past health conditions can also elevate your risk. These include conditions that affect blood flow or your limbs, such as:

Tips for dealing with varicose eczema

Tips for caring for your varicose eczema include:

Washing gently

Use a mild liquid cleanser that is free of preservatives and fragrance when washing your legs to help remove scales, crusts, and bacteria.

Rinse off with lukewarm or cooler water. Lightly pat the water from your skin with a clean towel, keeping a bit of water on it.

Using emollient moisturizer

Apply a thick moisturizer such as petroleum jelly to help seal in moisture and protect your skin. Do this when your skin is damp after bathing and throughout your day.

Stay away from products that can dry out or irritate your skin such as those that are scented, have preservatives, and contain calamine.

Raising your legs above your heart

Do this every 2 hours for 15 minutes to ease swelling and improve blood flow. Also, keep your legs propped up on pillows while you sleep.
