Stasis dermatitis: when the eczema is on your lower legs

Itchy, dry, discoloured skin around the ankles — often with swelling that used to go down overnight and now doesn't — is a specific thing with a specific cause. Stasis dermatitis is eczema driven by circulation, and it is one of the few kinds where treating the skin on its own will never be enough.

A plain-language explainer · Not medical advice — leg swelling and leg skin changes should be assessed by a doctor

What's actually happening

The veins in your lower legs have one-way valves whose job is to push blood back up toward the heart. When those valves weaken, fluid leaks into the tissue of the leg and it swells. That pooling is the "stasis" in the name, and the underlying problem has a name of its own: venous insufficiency. The skin changes are downstream of it.

Dermatologists estimate that somewhere around 15 to 20 million people over 50 in the United States have this. Risk rises with age, and it can also follow a leg injury, a blood clot, or surgery.

What it looks like, and how it progresses

It usually appears near the ankles and on the lower legs. Anywhere else is rare.

Why the moisturizer keeps losing. If you treat stasis dermatitis as ordinary dry-skin eczema, you are treating the last step of a chain and leaving the first one running. Care for the skin, yes — but the fluid has to be dealt with too, or the skin problem simply comes back. That is the whole reason this one needs a doctor rather than a better cream.

What treatment addresses

Management works on two fronts at once: the circulation and the skin. On the circulation side that means things like compression, elevating the legs when sitting, regular exercise, and medical treatment of the venous insufficiency itself. On the skin side, moisturizing the dry areas. Dermatologists also suggest walking for ten minutes after a long stretch of sitting or standing, and checking the skin of your legs regularly.

What kind of compression, and whether it's safe for you, is a medical decision — compression is not universally appropriate and getting it wrong matters. Ask rather than assume.

Why this one is worth acting on early

Skin that stays swollen and inflamed on the lower leg is skin that breaks down more easily, and broken skin on a leg with poor circulation is slow to heal and vulnerable to infection. Getting on top of it early is a good deal easier than getting on top of it late. If the skin is open, weeping, rapidly worsening, or looks infected, that's a same-week conversation, not a wait-and-see — see the signs of infection.

If nobody has explained this to you before. A lot of people carry leg eczema for years being told to moisturize more, and quietly conclude they're failing at something simple. They aren't. This is a plumbing problem showing through the skin, and it needs the plumbing addressed. Asking "could this be venous?" is a reasonable question to put to your doctor.

Bring the pattern, not just the flare

Swelling that changes through the day and skin that shifts week to week are hard to describe from memory, and easy to under-report. Ollowen keeps the record and the photos, so what you show at the appointment is the actual course rather than the worst morning you happen to remember.
