Swollen ankles improve fastest with a combination of elevation, movement, and reducing the fluid buildup that caused them in the first place. Most cases of mild ankle swelling respond well to simple home strategies, but the approach depends on whether the swelling is in both ankles (usually a circulation or dietary issue) or just one (which can signal something more serious). Here’s what actually works and how to do it right.
Elevate Above Your Heart
Elevation is the single fastest way to get visible relief. The key detail most people miss: your ankles need to be above the level of your heart, not just propped on a footstool. Lying on a couch or bed with your legs resting on two or three stacked pillows gets the angle right. Gravity then helps fluid drain back toward your core instead of pooling in your lower legs.
Aim for about 15 minutes per session, three to four times a day. If you work at a desk, even a midday session and one before bed can make a noticeable difference. Consistency matters more than marathon elevation sessions.
Keep Your Ankles Moving
Sitting or standing still for long stretches is one of the most common triggers for ankle swelling. Your calf muscles act as a pump that pushes blood and lymph fluid upward, and that pump only works when you move. Ankle pumps are the simplest exercise to activate it: point your feet toward your knees as far as you can, then point them away from you as far as you can. Alternate back and forth for two to three minutes, and repeat two to three times per hour when you’re sitting for long periods.
Walking is equally effective. Even a five-minute walk around your office or home engages the calf muscles enough to get fluid circulating. If you’re on a long flight or car ride, ankle pumps in your seat are the next best thing.
Cut Back on Sodium
Your kidneys respond to excess sodium by holding onto more water, and that extra fluid can leak from small blood vessels into the surrounding tissue, especially in the ankles where gravity pulls it. The World Health Organization recommends keeping sodium under 2,000 mg per day, which is just under a teaspoon of table salt.
Most people consume far more than that without realizing it, because sodium hides in processed foods, restaurant meals, canned soups, deli meats, and even bread. Reading nutrition labels and cooking more meals at home are the two most practical ways to bring your intake down. You don’t need to eliminate salt entirely. Just staying under that 2,000 mg threshold can reduce fluid retention significantly within a few days.
Drink More Water, Not Less
It sounds counterintuitive, but staying well hydrated actually helps reduce swelling. When you’re dehydrated, your kidneys retain more sodium and water as a protective response, which worsens fluid buildup. Drinking enough water keeps sodium concentrations in your blood diluted, so your kidneys release excess fluid normally rather than hanging onto it. There’s no magic number that works for everyone, but if your urine is pale yellow, you’re generally in good shape.
Try Compression Stockings
Compression stockings apply graduated pressure to your lower legs, squeezing fluid upward and preventing it from pooling around the ankles. They come in different pressure levels measured in mmHg, and the right level depends on how much swelling you have.
- 15 to 20 mmHg (mild): Good for very early or occasional swelling, travel days, or long shifts on your feet. Available over the counter without a prescription.
- 20 to 30 mmHg (moderate): The most commonly prescribed level for persistent mild to moderate swelling. Often recommended after the swelling has been reduced and you want to keep it from coming back.
- 30 to 40 mmHg (firm): Used for more significant swelling that doesn’t respond to lighter compression. Typically fitted by a healthcare provider.
Put them on first thing in the morning before swelling has a chance to build up during the day. If you wait until your ankles are already puffy, they’re harder to get on and less effective.
Gentle Lymphatic Drainage
This isn’t a regular massage. Lymphatic drainage uses very light, skin-stretching pressure to move trapped fluid toward your lymph nodes, where it can be reabsorbed. Firm, deep pressure actually blocks fluid flow, so lighter is better.
Start by placing your hands under your ankle bones on the back of your leg. Using a relaxed hand, gently stretch the skin upward toward your knee, hold for three seconds, then release. Next, place your hands on top of your foot near your toes and stretch the skin toward your ankle, hold for three seconds, and release. You can also gently pull the skin of each toe toward the ankle, one at a time. Repeat the full sequence 10 times per session. The touch should be so light it barely moves the skin.
Check Your Medications
Certain blood pressure medications are a surprisingly common cause of ankle swelling. One class in particular, calcium channel blockers, causes ankle swelling in 1 to 15% of patients at standard doses. At higher doses taken long-term, that number can exceed 80%. If your ankle swelling started or worsened after beginning a new medication, that connection is worth exploring with your prescriber. Combining the medication with another type of blood pressure drug has been shown to cut the swelling rate roughly in half in some cases.
Other medications that can cause fluid retention include certain diabetes drugs, steroids, and some anti-inflammatory pain relievers. Don’t stop any medication on your own, but knowing this connection exists helps you have the right conversation.
What Epsom Salt Soaks Won’t Do
Epsom salt foot soaks are popular advice for swollen ankles, but there’s no clinical evidence they reduce swelling. Warm water may feel soothing, and that’s fine, but the magnesium in Epsom salt isn’t absorbed through skin in meaningful amounts. If your swelling is persistent, you’re better off spending that time with your legs elevated above your heart.
When Swelling Signals Something Serious
Swelling in both ankles that comes and goes with activity, heat, or salt intake is usually benign. Swelling in just one leg is a different story. A blood clot in a deep vein, known as DVT, typically causes swelling on one side along with pain or tenderness (often worse when standing or walking), warmth in the swollen area, and skin that looks red or discolored. You may also notice veins near the surface appearing larger than usual.
The danger with DVT is that the clot can break loose and travel to the lungs. Signs of that include sudden chest pain, shortness of breath, coughing up blood, or feeling lightheaded or faint. That’s an emergency room situation, not a wait-and-see one.
Swelling that develops suddenly, feels hot to the touch, comes with fever, or doesn’t improve after several days of consistent elevation and movement also warrants prompt medical evaluation. Persistent swelling in both legs can occasionally point to heart, kidney, or liver problems, particularly if it’s accompanied by shortness of breath or unexplained weight gain.
