Venous stasis, also called chronic venous insufficiency, is treated with a combination of compression therapy, leg elevation, targeted exercise, and in some cases minimally invasive procedures to close off damaged veins. Most people start with conservative measures that can significantly reduce swelling, pain, and skin changes. The severity of your condition determines how aggressive treatment needs to be.
Compression Therapy: The Foundation of Treatment
Compression stockings are the single most important tool for managing venous stasis. They work by applying graduated pressure to your lower legs, helping push blood back up toward your heart and preventing it from pooling in damaged veins. The key is matching the pressure level to the severity of your symptoms.
For mild symptoms like occasional heaviness or achiness after standing, stockings in the 10 to 20 mmHg range are effective. Studies show that even this low level of pressure reliably reduces swelling and discomfort, particularly for people who stand for long periods at work. For moderate venous insufficiency with visible swelling or varicose veins, 20 to 30 mmHg stockings provide stronger support and have been shown to significantly relieve aching, pain, leg cramps, and restlessness. Higher pressures (30 to 40 mmHg or above) are reserved for more advanced disease, including active skin changes or ulcers, and typically require a prescription.
An evidence-based consensus statement in Phlebology recommends starting with the lowest pressure that relieves your symptoms, then stepping up only if needed. Knee-high stockings work for most people. Put them on first thing in the morning before swelling sets in, and wear them throughout the day.
Leg Elevation and Daily Habits
Elevating your legs above the level of your heart three or four times a day for about 15 minutes each session can provide immediate pain relief and visibly reduce swelling. This is one of the simplest and most effective things you can do, and it works because gravity helps blood drain from your lower legs instead of pooling there.
Beyond elevation, avoid sitting or standing in one position for extended periods. If your job keeps you at a desk, take brief walking breaks every 30 to 60 minutes. If you stand all day, shift your weight frequently and flex your calves. Maintaining a healthy weight also reduces the pressure on your leg veins.
Exercises That Improve Venous Return
Your calf muscles act as a pump that squeezes blood upward through your veins with each contraction. Strengthening this pump is one of the most effective long-term strategies for managing venous stasis. A systematic review in the Journal Vascular Brasileiro found that exercise training increased the volume of blood ejected from the legs with each muscle contraction and reduced the amount of blood left pooling in the veins afterward.
The exercises studied were straightforward: heel raises (going up on your toes and lowering back down), calf stretches, ankle circles, treadmill walking at moderate intensity, and resistance exercises using elastic bands. Programs that showed results typically involved two to three sets of 10 repetitions for strengthening exercises, combined with 10 to 20 minutes of walking. Some programs were as simple as six weeks of daily heel raises paired with walking and calf stretching.
For people with earlier-stage disease, exercise actually improved blood flow direction in the veins, meaning it helped fix some of the underlying backflow problem. In more advanced cases, exercise still strengthened the calf pump and improved ankle flexibility, though it didn’t reverse the structural vein damage. Wearing compression stockings during exercise amplifies the benefits by combining external pressure with the internal pumping action of your muscles.
Treating Skin Changes and Stasis Dermatitis
As venous stasis progresses, the skin on your lower legs often becomes itchy, discolored, dry, and inflamed. This is called stasis dermatitis, and it needs its own layer of treatment on top of compression and elevation. Keeping the skin well moisturized with a fragrance-free emollient is the baseline. Apply it daily to prevent cracking and breakdown.
For active flares with redness and itching, mid- to high-potency topical corticosteroid creams can be used intermittently. These should not be applied continuously for long stretches, since the skin in this area is already compromised and prolonged steroid use can thin it further. If you notice your skin becoming increasingly brown, hard, or leathery, that signals worsening disease and the need for more aggressive management of the underlying venous problem.
Caring for Venous Ulcers
Open sores on the lower legs, called venous ulcers, are the most serious complication of untreated venous stasis. Treatment centers on two things: appropriate wound dressings and consistent compression.
Dressing selection depends on how much fluid the wound is producing. Wounds with heavy drainage do best with foam dressings, which are made of absorbent polyurethane that pulls excess moisture away from the skin. Drier wounds need a more moisture-retaining dressing like a hydrocolloid, which keeps the wound bed from drying out. The goal in both cases is maintaining a moist healing environment without soaking the surrounding skin.
For ulcers that are slow to heal, a blood-flow-enhancing oral medication can be added to compression therapy. A meta-analysis found that adding this medication increased ulcer healing rates to about 63%, compared with roughly 41% for standard care alone. This is typically reserved for stubborn wounds that aren’t responding to compression and proper wound care on their own.
Minimally Invasive Procedures
When conservative measures aren’t enough, or when there’s significant backflow in the larger veins of the leg, procedures can close off the damaged veins and reroute blood through healthier ones. These are done in outpatient settings, usually with local anesthesia, and you can walk the same day.
Radiofrequency ablation uses heat delivered through a thin catheter to seal the vein shut. It has strong long-term results: at five years, about 88% of treated veins remain closed, and complication-free rates are around 90%. Laser ablation works similarly but uses laser energy instead of radiofrequency. Its five-year closure rate is somewhat lower at around 75%, with a higher rate of minor side effects like bruising and tenderness.
Foam sclerotherapy is another option, where a foam solution is injected into the vein under ultrasound guidance to irritate the vein wall and cause it to collapse. It’s often used for smaller branch veins or in combination with thermal ablation for more complete treatment. Not everyone is a candidate: people with deep vein clots, clotting disorders, or pregnancy are typically excluded.
Recovery from these procedures is quick. Most people return to normal activities within a day or two and wear compression stockings for one to two weeks afterward. The closed vein is gradually absorbed by your body, and blood naturally redirects through deeper, healthier veins.
What to Expect Over Time
Venous stasis is a chronic condition, which means treatment is ongoing rather than a one-time fix. Compression, elevation, and exercise need to become daily habits. The swelling and heaviness typically improve within the first few weeks of consistent compression use, though skin discoloration from long-standing disease often takes months to fade and may never fully resolve.
Even after a successful procedure, the underlying tendency toward venous insufficiency remains. New veins can develop the same problems over time, so continuing with compression stockings and calf-strengthening exercises helps protect your results. If you’ve had a venous ulcer, the risk of recurrence is significant without ongoing compression, making daily stocking use especially important for prevention.
