Stasis dermatitis: the rash that starts in your veins

Name: Stasis dermatitis: why do ankles turn brown and swell?
Creator: Chicatella Editorial Team
Published: 2026-08

In the morning, your ankle looks almost normal. By evening, your sock leaves a deep line in it. Over time, the skin starts to itch, darkens and turns dry or inflamed. With stasis dermatitis, the rash often isn’t the first problem. It’s the visible trace of pressure that has been building up in the veins of your legs for a long time.

It happens because blood and fluid don’t flow back up the veins well enough, so they pool in the lower leg. That’s why it starts around the ankle, where the pressure is highest. And that’s why putting something on your skin won’t fix the vein problem behind it. Still, good skin care is an important part of managing it, because the skin there is dry, sensitive and easily hurt.

The key points in 30 seconds

Four things worth knowing

Where it usually starts

Around the ankles and on the lower shins.

What’s behind it

Because of poor blood flow back through the veins, blood and fluid pool in the legs.

Why the skin turns brown

Red blood cells leak into the surrounding tissue, and their pigment can stay in the skin for a long time.

What you need

Care for the pressure in your veins and, at the same time, daily protection for dry skin.

If one leg suddenly becomes much more swollen, hot or painful, that’s not something to figure out online.

Visual guide

What the skin around your ankle shows over time

Seven cards: how the changes begin, why the skin darkens, what happens underneath and what really helps. Swelling, dryness and a brown band around the ankle are three signs worth knowing. The drawings are simplified; a doctor makes the diagnosis.

Browse→

Calm in the morning, swollen at night

The first sign is often swelling that grows during the day and leaves a deep sock line by evening. It goes down overnight.

Dry, flaky, itchy

The skin on your shin holds on to water less well. It becomes dry, flaky and tight, and starts to itch or burn.

The skin darkens

Red blood cells escape from overfilled veins. Their iron stays in the skin and stains it brown. It isn’t dirt, and it won’t wash off.

The cause is under the skin

The valves in your veins don’t close tightly, so blood doesn’t flow smoothly upward and pools in the lower leg. The skin just shows the result.

What really helps your veins

Compression stockings, raising your legs and walking push blood back up. A cream can’t do that. Your doctor decides the type and strength of compression.

What helps your skin

Regular care lays a protective layer over dry skin and holds water in. Less dryness means less itching and less scratching that could break the skin.

When not to wait

An open wound that won’t heal, oozing, yellow crusts, a hot and painful leg or redness that spreads quickly: a doctor needs to look at this, not a cream.

Quick questions

Quick questions before you read on

Is stasis dermatitis contagious?

No. It’s caused by pressure in the veins of the legs and doesn’t spread from person to person through touch or shared towels.

Can it show up on just one leg?

Yes. Both legs are affected more often, but it can appear on just one, for example after a past deep vein thrombosis or an injury to that leg. But if one leg suddenly swells up a lot, you need a doctor to check it; more in the section When you need help fast.

Is a brown patch just a bruise?

Not necessarily. A bruise fades within a few weeks. The brown color in stasis dermatitis appears because iron-containing pigment from broken-down red blood cells settles in the skin, and it can stay there for a very long time. More in the section on the brown color.

Can a cream fix the cause?

No. A skin care product works on the surface of the skin. It helps reduce dryness and moisture loss. It doesn’t change the pressure in your veins. That’s why this condition often calls for two different kinds of support.

Can I just start wearing strong compression stockings on my own?

Picking strong compression blindly isn’t a good idea. Compression is often very helpful for vein problems, but a health professional should decide the strength and whether it’s right for you, especially if you have diabetes, artery disease, heart failure or an open wound. More in the section on compression.

Is stasis dermatitis the same as a bacterial skin infection?

No, though they can look alike. Stasis dermatitis usually develops over a longer time, often itches and can affect both legs. A bacterial skin infection (cellulitis) often spreads quickly, is more painful and warm, and can come with fever and feeling unwell. There’s a comparison in the section on the diagnostic trap.

Can the brown color go away completely?

Often not completely. Dryness, itching and inflammation can improve much faster than the color, because the pigment sits deeper in the skin. Some of it may fade over the years, but there’s no promise it will disappear.

Daily pattern

Don’t start with the rash. Start with the clock.

With vein problems, swelling follows the clock. There’s little in the morning, it grows during the day and peaks in the evening. If your ankle does the same, that’s an important clue.

Morning

The ankle looks almost normal

After a night lying down, blood has drained out of the leg. Swelling is at its lowest, and the skin isn’t tight.

SWELLING

Late morning · sitting or standing

Pressure in the leg builds

When I don’t move, my calf muscles don’t help. Blood and fluid slowly collect low in the leg.

SWELLING

Afternoon

The leg feels heavy and tight

The swelling is obvious. Shoes feel tighter, the skin feels tight and may start to itch.

SWELLING

Evening

The sock leaves a deep mark

The peak of the day. The sock line is deep and takes longer to fade.

SWELLING

I raise my leg or lie down

The swelling goes down

Now gravity is working for me: blood drains back toward the heart and the ankle partly settles. In the morning, the cycle starts again.

SWELLING

Simplified diagram. Early on, the swelling disappears overnight. As the problem progresses, it no longer goes away completely by morning.

This pattern is a clue, not a diagnosis. Legs can also swell because of the heart, kidneys, medications, the lymph system or a blood clot. That’s why a doctor should find the cause.

How your leg sends blood back up

Blood has to travel from your leg back up. Two things help it get there.

Your heart pushes blood down into your leg, but on the way back it has to fight gravity. That’s why your leg has a pump (your calf muscles) and little doors (the valves in your veins) so blood doesn’t flow back down.

1 · Standing still

The pump is off

Your calf muscles are resting, so blood gets no push upward. It collects low, around the ankle. This is the position that’s hardest on your ankle.

2 · Taking a step

The pump is on

With every step, your calf muscle squeezes and pushes blood upward. The valves close behind it like one-way doors so it can’t flow back. That’s why walking helps.

3 · When the doors leak

This is where the trouble starts

If the valves don’t close tightly, blood flows back down after every step. Pressure stays low in the leg for months and years. Over time, that constant pressure damages the tiny blood vessels and the skin around the ankle.Source↗︎

In plain words: whatever helps the pump and the doors helps your skin. Walking, raising your legs and compression stockings do exactly that. A cream can’t, but it can take care of the skin that the pressure keeps drying out.

Valves aren’t the only possible cause. The same thing can happen after a deep vein thrombosis, with a blocked vein, a stiff ankle or weak calf muscles.

Pigment

A brown patch isn’t dirt, and it isn’t necessarily a bruise

The color comes from inside. It forms from iron left in the skin when red blood cells break down. Here’s how it happens, in five steps.

Pressure in tiny vessels

Long-term pressure in the veins carries over to the smallest blood vessels in the skin around the ankle.

Blood cells escape the vessel

The vessel wall gives way. Red blood cells and fluid pass into the surrounding tissue.

The blood cells break down

Outside the vessel, blood cells don’t survive. They break down, but their iron stays behind.

Iron stains the skin

Iron-containing pigment (hemosiderin) settles in the skin. From the outside, we see it as a brown band.

The body cleans up slowly

Immune cells carry the pigment away, but very slowly. That’s why the color lasts a long time, even after the skin calms down.

Simplified diagram of the process, not a picture of blood.

What this means for the color

The color doesn’t fade as quickly as dryness or itching.
The skin can calm down while the pigment stays for a long time.
An ointment doesn’t repair vein valves and doesn’t erase pigment that sits deep in the skin.

What skin care can do

Consistent care keeps the surface of your skin softer, less dry and better protected. Less dryness means less itching, less scratching and less chance of the skin breaking open.

Two different roads

“Poor circulation” goes two ways. They’re not the same.

Blood travels down to the foot through the arteries and up back to the heart through the veins. Stasis dermatitis is a problem with the road up. The signs are different, so it’s worth telling them apart.

Vein · the road up

Blood pools in the leg

•the ankle swells, more in the evening
•the leg feels heavy and warm
•the skin around the ankle turns brown
•better when I raise my leg

This is stasis dermatitis.

Artery · the road down

The foot gets too little blood

•the foot is cold, pale or bluish
•it hurts when walking or at night
•small sores on the toes heal poorly
•worse when I raise my leg

This isn’t stasis dermatitis. You need a checkup.

Why this matters: with a vein problem, compression stockings help a lot. But if the arteries are also weak, strong compression can do harm. That’s why, before prescribing it, a doctor does a simple test comparing blood pressure at the ankle and the arm (ABPI).ESVS↗︎

A person can have both problems at once. This diagram doesn’t make a diagnosis.

Over time

Five messages your skin sends over time

Your sock leaves a deeper mark

Swelling in the evening, a heavy, tight feeling. Often the first sign, and one people put down to being tired or to hot weather.

The skin starts to itch, burn or peel

The skin barrier becomes drier and more vulnerable. This is the first point where regular care really pays off. More on that in our article on dry skin.

A brownish or purplish band appears around the ankle

Pigmentation from blood products passing into the tissue. This color is the slowest to fade.

The skin and the tissue underneath get harder

Long-term inflammation can change the tissue under the skin, so the lower leg becomes hard, painful and sometimes shaped like an upside-down bottle. The medical term is lipodermatosclerosis.Source↗︎

A small wound appears that won’t close

A venous ulcer is no longer a job for everyday cosmetic care. It needs professional wound care and treatment of the veins.Slovenian Ministry of Health↗︎

For the curious: a simplified CEAP scale

C3 · swelling

C4a · pigmentation or eczema

C4b · hardened tissue under the skin or white, scar-like patches

C4c · fan-shaped tiny blood vessels around the ankle

C5 · healed ulcer

C6 · open ulcer

This scale helps doctors describe the condition. It’s not an online test for grading yourself. The medical term for the white, scar-like patches is atrophie blanche.

The diagnostic trap

A red leg isn’t always an infection

A red, warm, swollen shin looks a lot like a bacterial skin infection. But often it isn’t one.

What researchers found

4 in 10

people diagnosed with a “skin infection of the leg” got a different diagnosis when they were checked again.

Review of 9 studies with 1,600 people. Results varied a lot between studies.Nightingale 2023↗︎

What it really was

More than half of these “infections” were stasis dermatitis or swelling caused by lymph not draining well.

Why this matters: antibiotics don’t help dermatitis, but skin care and compression do. And the other way around: a real infection must not be missed.

Warning signs

When you need help fast

Right away / emergency

sudden shortness of breath, chest pain, fainting or coughing up blood;
the foot suddenly turns very cold, pale or bluish;
severe pain that came on quickly, or loss of feeling.

With signs like these, call 911.

The same day

one leg suddenly swells a lot, hurts or feels warmer;
redness spreads quickly;
you have a fever, chills or feel really unwell;
an open wound, pus, a bad smell or heavy oozing appears.

Book a checkup

your ankles keep swelling;
the skin around your ankle is turning brown, itching or peeling;
the skin is getting hard or painful;
a small wound won’t close;
the problem continues despite regular care;
you’re not sure if it’s your veins, arteries, an allergy or an infection.

The checkup

A doctor doesn’t just look at the rash. They look at the whole leg.

where the change is

whether one or both legs are affected

whether the swelling goes down by morning

whether you have varicose veins, a past blood clot, an injury or surgery

which medications you take

what the pulses in your foot are like

a vein ultrasound, when blood flow and valves need checking

a check of blood flow in the arteries, if narrowing is suspected

an allergy patch test, if the problem persists or keeps coming back after using products

a biopsy is often avoided on skin that heals poorly, unless another disease has to be ruled out

Questions you can take to your appointment

Is the swelling from my veins, my lymph system or another condition?
Do I need a vein ultrasound?
Is compression right for me, and what kind?
How should I care for my skin under compression?
What should I do if oozing or a wound appears?

The core idea

Treat only the skin, and the pressure stays. Treat only the veins, and the skin stays vulnerable.

Two locks, two keys

Lock 1

Pressure in the veins

Key

compressionwalking and raising your legsvein care

Lock 2

Dry, vulnerable skin

Key

gentle washingdaily skin care

No single key opens both. A cream doesn’t lower the pressure in your veins. Compression doesn’t nourish dry skin. You need both.

Job 1

Reducing pooling and pressure

properly fitted compression;
walking and moving your ankle;
breaking up long stretches of sitting or standing;
raising your legs;
support with body weight, without judgment;
a vein checkup;
if needed, procedures such as closing a faulty vein, sclerotherapy or other vascular treatments.

Job 2

Protecting the skin barrier

gentle washing;
lukewarm water instead of very hot;
a suitable skin care product every day;
reducing moisture loss;
protecting the skin from scratching and bumps;
treating badly inflamed skin with a medication your doctor prescribes, if needed;
professional care if the skin is broken or oozing.

Compression

A stocking that squeezes your ankle does what a cream can’t

A compression stocking presses on your leg from the outside and helps blood flow back up. What do the 2025 medical guidelines say about it?

STRONGLY RECOMMENDED

If there’s an open venous wound on the leg

Here the evidence is clear. Wounds heal much better with compression.

+31more wounds out of 100 heal within a year when people wear compression

RECOMMENDED, WITH CAUTION

If the leg swells, feels heavy and itches, but there’s no wound

Compression is still recommended, but there’s less evidence for each individual symptom. It helps many people, but there’s no guarantee.

How a stocking squeezes

Knee
lightly

Ankle
tightest

It squeezes hard at the bottom and less and less toward the knee. That’s how it pushes blood upward. Your doctor decides how tight it should be.

Five things good to know

It squeezes tightest at the ankle and less toward the knee. That’s not a defect, it’s how it should be.

It has to be the right size. Get your leg measured; don’t guess.

Put it on in the morning, right after you get up. That’s when your leg is least swollen and it goes on most easily.

Hard to put on because of your hands or back? There are aids for putting them on. Ask at the pharmacy.

How strong and which kind: your doctor decides. Especially if you have diabetes, poor arteries, heart failure or an open wound.

Routine

What you can do today, without turning your life into a medical project

Morning

take a quick look at both legs;
check for a new small wound, unusual swelling or a change in color;
put on prescribed compression when the swelling is lowest;
if you use a skin care product in the morning, let it absorb well before putting on the stocking, and follow the stocking’s instructions.

During the day

don’t stay completely still for hours;
take a few steps often;
move your ankle up and down;
rise up onto your toes now and then, if you can do it safely;
when sitting, don’t tuck your legs tightly under the chair;
protect your shins from bumps.

Evening

take off compression as instructed;
wash your skin gently with lukewarm water;
don’t rub it with a towel;
apply suitable care to dry, unbroken skin;
give very dry spots extra protection with a richer ointment;
raise your legs comfortably for a while.

We deliberately don’t give a universal number of repetitions or time for raising your legs. The examples above are general examples; anyone with a more serious heart or vascular condition should plan this with their doctor.
