Quick Answer
Stasis dermatitis is a common inflammatory skin condition on the lower legs caused by poor circulation. When the valves in your leg veins weaken, blood can pool, creating pressure that leads to swelling, itching, and distinctive brown discolouration. It usually affects adults over 50, especially those with varicose veins, obesity, or a history of blood clots. Treatment focuses on improving circulation through daily compression stockings, elevating your legs, and regular exercise. Without proper management, the affected skin can become hard or develop painful, open sores known as venous ulcers.
Clinical Context
Stasis dermatitis (venous eczema) is a common inflammatory skin condition of the lower legs caused by chronic venous insufficiency. Incompetent venous valves lead to increased venous pressure, causing fluid leakage, inflammation, and characteristic skin changes. It affects approximately 15-20 million Americans, more common after age 50. The condition progresses from edema and erythema to hemosiderin deposition (brown discoloration), lipodermatosclerosis (hardening), and ultimately venous ulceration in 500,000 people annually. It's a chronic condition requiring ongoing management.
Symptoms
- Itchy, scaly skin on lower legs
- Brown discoloration
- Swelling
- Open sores in severe cases
- Skin may become hard and fibrotic
Severity & Progression
Causes & Risk Factors
- Chronic venous insufficiency
- Deep vein thrombosis history
- Varicose veins
- Obesity
- Prolonged standing
Treatment & Management
Compression therapy is the cornerstone of treatment - graduated compression stockings (20-30 or 30-40 mmHg) improve venous return and reduce edema. Leg elevation above heart level for 30 minutes, 3-4 times daily, complements compression. Acute inflammation is treated with medium-potency topical corticosteroids for 1-2 weeks. Moisturizers maintain skin barrier. Wound care is essential for ulcerations. Underlying venous disease may require endovenous ablation, sclerotherapy, or surgery. Diuretics are not helpful and may worsen dehydration.
- Compression stockings
- Leg elevation
- Treating venous disease
- Topical steroids for inflammation
- Moisturizers
- Wound care for ulcers
Red Flags & Complications
Seek medical attention if you experience any of the following:
- Venous ulcers (most common leg ulcer type)
- Secondary bacterial infection (cellulitis)
- Lipodermatosclerosis (hard, fibrotic skin)
- Contact dermatitis from topical treatments
- Reduced quality of life
- Chronic pain
Self-Care Tips
- Wear compression stockings daily as prescribed
- Elevate legs above heart level several times daily
- Avoid prolonged standing or sitting
- Exercise regularly (walking improves calf pump)
- Moisturize skin daily to prevent cracking
- Protect legs from injury
- Maintain healthy weight

Frequently Asked Questions
What does stasis dermatitis look and feel like at the start?
In its early stages, you will usually notice swelling around your ankles, especially at the end of the day. The skin on your lower legs may feel itchy, turn red, and look slightly scaly. As it progresses, the pooled blood causes fluid to leak into the skin, gradually creating a permanent brown discolouration and making the skin feel hard or tight.
Why am I getting this rash on my lower legs?
It is directly linked to chronic venous insufficiency. Normally, one-way valves in your leg veins push blood back to your heart. If these valves weaken or fail, blood pools in the lower legs, increasing pressure. This pressure forces fluid out of the blood vessels and into the surrounding tissues, triggering inflammation, swelling, and the characteristic skin changes of stasis dermatitis.
How do I get rid of stasis dermatitis?
While it is a chronic condition that requires ongoing management rather than a quick cure, you can control it effectively. The most important step is wearing graduated compression stockings daily to improve circulation. Elevating your legs above your heart for 30 minutes a few times a day also helps. Doctors may prescribe topical steroids to calm active inflammation and recommend thick moisturisers to protect your skin barrier.
What happens if I ignore the swelling and discolouration?
If left untreated, stasis dermatitis will likely worsen. The skin on your lower legs can become permanently scarred, hard, and fibrotic, which is a condition called lipodermatosclerosis. More severely, the fragile skin can easily break down into open wounds called venous ulcers. These painful sores are very difficult to heal and significantly increase your risk of developing a serious bacterial infection like cellulitis.
Are there things I can do at home to prevent it from getting worse?
Yes, home care is essential. Avoid standing or sitting still for long periods; if you must, take frequent breaks to walk around. Walking activates your calf muscles, which act as a pump to push blood back up your legs. Always wear your compression stockings as prescribed, keep the skin deeply moisturised, and elevate your legs above heart level whenever resting.
Will taking water pills help reduce the swelling in my legs?
A common misconception is that standard diuretics, or water pills, will fix the swelling from stasis dermatitis. Because the fluid buildup is caused by mechanical vein failure and local pressure rather than a systemic fluid overload, diuretics are generally not helpful. In fact, they can worsen dehydration and cause other side effects. Always manage this swelling with physical compression and elevation instead.
When should I see a doctor about my leg swelling and rash?
You should see a doctor as soon as you notice persistent lower leg swelling, brown discolouration, or chronic itching. Prompt evaluation can prevent irreversible skin changes. Seek immediate medical attention if the skin becomes hot, exceptionally red, intensely painful, or if you develop an open sore, as these are signs of infection or ulceration that require urgent professional wound care.
How can ScanSkinAI help me with suspected stasis dermatitis?
ScanSkinAI can analyze photos of the rash and swelling on your lower legs to provide an initial screening. It can help identify visual features commonly associated with stasis dermatitis, such as typical brown discolouration. However, our AI is an educational screening aid and cannot replace a medical evaluation. A doctor is required to formally diagnose venous insufficiency and prescribe appropriate compression therapy.
