Elevating your legs, applying ice, staying active, and reducing salt intake are the most effective ways to bring down swollen ankles. The right approach depends on whether the swelling is from a long day on your feet, an injury, or something more persistent. Most cases of temporary ankle swelling respond well to simple home strategies, but swelling that lingers for weeks or appears suddenly in one leg can signal something that needs medical attention.
Elevate Your Legs Above Your Heart
The single most effective thing you can do for swollen ankles is get your legs up, and height matters. Your feet need to be above the level of your heart for gravity to help drain fluid back toward your core. Lying on a couch with your legs propped on two or three pillows works well. If you can’t get them that high, resting your feet on an ottoman or coffee table still helps slow the downward pull of gravity, even if results come more slowly.
Try to stay in this position for 15 to 30 minutes at a time, several times a day. Many people prop their feet on a low stool and wonder why the swelling doesn’t budge. The key is getting your ankles higher than your chest, which usually means lying down rather than sitting in a recliner.
Ice the Swelling
Cold reduces swelling by narrowing blood vessels and slowing the flow of fluid into the tissue. Apply an ice pack or cold compress for 10 to 20 minutes, three or more times a day. Wrap the ice in a thin towel to protect your skin, and don’t leave it on longer than 20 minutes at a stretch. Icing is especially useful after an injury or a long period of standing, and it pairs well with elevation.
Use Compression
Compression socks or wraps apply steady pressure that keeps fluid from pooling in your lower legs. You can find graduated compression socks at most pharmacies. These are tighter at the ankle and looser toward the knee, which gently pushes fluid upward. If you’re wrapping an injured ankle with an elastic bandage, start at the toes and work upward, keeping the wrap snug but not tight enough to cause numbness or tingling.
Move Your Feet and Calves
Your calf muscles act as a pump that pushes blood back up toward your heart every time they contract. When you sit or stand still for hours, that pump shuts off, and fluid settles into your ankles. Even small movements can restart it.
The simplest exercise is ankle pumps: point your toes down, then pull them up toward your shin. Repeat this 10 to 15 times. You can do it sitting at a desk or lying in bed. Heel raises are another good option. Stand and slowly lift yourself onto your toes, hold for a second, then lower back down. Two to three sets of 10 repetitions strengthens the calf muscles over time and improves your body’s ability to circulate fluid. Circular foot movements, walking for even 10 minutes, and calf stretches all help as well. The goal is consistent, daily activity rather than one intense session.
Cut Back on Sodium
Salt causes your body to hold onto water, and that extra fluid often shows up first in the ankles. Most people consume far more sodium than they realize. For people dealing with persistent edema, research from Georgetown University’s nephrology department recommends keeping daily sodium between 1,375 and 1,800 milligrams. For context, a single fast-food meal can easily contain 1,500 milligrams or more.
The biggest sources of hidden sodium are processed and packaged foods: canned soups, deli meats, frozen meals, bread, and condiments. Cooking at home with fresh ingredients and seasoning with herbs, lemon, or spices instead of salt can make a noticeable difference in swelling within a few days.
Consider Magnesium
Taking 200 to 400 milligrams of magnesium daily may help reduce swelling, particularly if your levels are low. Magnesium plays a role in fluid balance and muscle function, and many adults don’t get enough from diet alone. Foods rich in magnesium include dark leafy greens, nuts, seeds, and whole grains. If you have kidney or heart problems, check with your doctor before starting a supplement, since your body may not clear excess magnesium efficiently.
Check Your Medications
Several common medications cause ankle swelling as a side effect. Blood pressure drugs called calcium channel blockers, particularly amlodipine and nifedipine, are among the most frequent culprits. They widen certain blood vessels, which increases pressure inside the tiny capillaries and pushes fluid into surrounding tissue. If you take one of these and notice swelling, your doctor may be able to switch you to a newer formulation with lower rates of edema, or add a second medication that counterbalances the effect.
Diabetes medications in the thiazolidinedione class (like pioglitazone) can also cause fluid retention by increasing how much sodium and water your kidneys hold onto. NSAIDs, certain steroids, and some antidepressants can contribute as well. Never stop a prescribed medication on your own, but if your swelling started around the same time as a new prescription, that’s worth discussing with your provider.
One Leg vs. Both Legs Matters
Swelling in both ankles usually points to something systemic: too much salt, prolonged sitting, medication side effects, or in more serious cases, problems with the heart, kidneys, or liver. This type of swelling typically builds gradually over days or weeks and isn’t usually painful to the touch.
Swelling in just one leg is a different situation. A blood clot (deep vein thrombosis) is the most concerning possibility, especially if the swelling came on within the past 72 hours and is accompanied by calf pain or tenderness, warmth in the skin, visible swelling that makes one calf noticeably larger than the other, and pitting (when you press the skin and it holds the indent). If the affected calf is more than 3 centimeters larger than the other side, that’s a clinical red flag. Blood clots require urgent treatment because a clot can break loose and travel to the lungs.
Infections (cellulitis) can also cause sudden, one-sided swelling with redness, warmth, and tenderness. Both blood clots and infections need prompt medical evaluation.
When Swelling Signals Something Bigger
Persistent swelling in both legs that doesn’t respond to elevation, salt reduction, and movement may reflect an underlying organ problem. Heart failure causes fluid backup that often shows up as ankle swelling along with shortness of breath and fatigue. Kidney disease can cause swelling alongside changes in urination. Liver disease may produce swelling combined with abdominal bloating or yellowing of the skin. Thyroid problems can lead to puffiness along with fatigue and unexplained weight gain.
These conditions develop gradually, and ankle swelling is often one of the earliest visible signs. If your ankles stay swollen despite consistent home care, or if the swelling is getting worse over weeks, that pattern is worth investigating. Swelling and pain from an injury that haven’t improved after a couple of days also warrant a visit, since what feels like a mild sprain could be a fracture.
A Daily Routine That Works
For most people dealing with non-emergency ankle swelling, combining several strategies works better than relying on just one. A practical daily routine might look like this: keep sodium under 1,800 milligrams, do ankle pumps and heel raises two to three times throughout the day, take a 10 to 15 minute walk, elevate your legs above heart level for 20 to 30 minutes in the evening, and wear compression socks during long periods of sitting or standing. Ice as needed after particularly active or long days. These small, consistent habits tend to produce noticeable results within a week for swelling that’s driven by gravity, inactivity, or diet.
