Foot and ankle edema improves fastest with a combination of elevation, compression, movement, and dietary changes. Most mild to moderate swelling responds well to these strategies within days, though the underlying cause determines whether it fully resolves or needs ongoing management.
Elevate Your Legs Above Your Heart
The simplest way to start moving fluid out of swollen feet is gravity. Lie down and prop your legs on pillows so your feet sit above the level of your heart. This position allows pooled fluid to drain back toward your core rather than fighting gravity in your lower legs. Aim for 15 to 20 minutes at a time, several times a day. Many people notice a visible difference after just one session, especially if the swelling is worst at the end of the day.
If lying flat isn’t comfortable, even sitting with your feet elevated on an ottoman or chair helps. The key is getting your feet higher than your hips. Avoid sitting with your legs dangling or crossed for long stretches, since both positions slow the return of blood and lymph fluid from your lower legs.
Use Compression Stockings
Compression stockings apply steady pressure that keeps fluid from settling in your tissues. They come in different pressure ratings measured in millimeters of mercury (mmHg), and the right level depends on how much swelling you have. For mild, everyday swelling from sitting or standing too long, stockings in the 10 to 15 mmHg range are effective at preventing and reducing fluid buildup. Research confirms that this light pressure range works well for occupational edema in people who sit or stand for extended periods.
For more persistent swelling, stockings rated 15 to 20 mmHg or 20 to 30 mmHg provide stronger compression. Studies comparing these two ranges found that both reduce swelling over a workday, but higher pressure produces a greater reduction. If you’re unsure which level to start with, 15 to 20 mmHg is a reasonable middle ground that’s available without a prescription at most pharmacies.
Put compression stockings on first thing in the morning, before swelling has a chance to build. They’re harder to pull on over already-swollen ankles, and they work best as prevention rather than treatment after the fact. Knee-high styles are usually sufficient for foot and ankle edema.
Do Ankle Pumps Throughout the Day
Your calf muscles act as a pump that pushes blood and fluid back up toward your heart. When you sit or stand without moving, that pump essentially shuts off and fluid accumulates. Ankle pumps are a simple exercise that reactivates it.
Sit or lie down with your legs extended. Point your toes toward your knees as far as you can, then point them away from you as far as you can. Alternate between these two positions for two to three minutes, repeating two to three times per hour. You can do this at a desk, on a couch, or in bed. Circular ankle rotations work similarly. The goal is consistent, frequent movement rather than one intense session.
Walking is another effective way to engage your calf muscles. Even a five-minute walk every hour makes a noticeable difference compared to sitting still. If mobility is limited, ankle pumps give you much of the same benefit without standing.
Cut Back on Sodium
Sodium causes your body to hold onto water, and excess sodium is one of the most common dietary contributors to swelling. The World Health Organization recommends staying under 2,000 mg of sodium per day, which is just under a teaspoon of salt. Most people consume well beyond that, largely from processed and restaurant foods rather than the salt shaker.
Canned soups, deli meats, frozen meals, bread, cheese, and condiments are some of the biggest sources of hidden sodium. Reading nutrition labels and choosing low-sodium versions of these staples can reduce your intake significantly. Many people who cut sodium notice their rings fit looser and their shoes feel less tight within a few days, as their body releases the extra water it was retaining.
Consider Magnesium
Magnesium plays a role in fluid balance, and some evidence suggests supplementation can help reduce edema. In one clinical study, patients with venous reflux disease who added 365 mg of magnesium oxide daily to their treatment regimen saw significantly greater improvement in edema scores after just two weeks compared to those who didn’t take magnesium. The effect was modest but measurable.
Magnesium-rich foods include dark leafy greens, nuts, seeds, beans, and whole grains. If you suspect a deficiency, a supplement in the 200 to 400 mg range is generally what’s used in studies. Magnesium works best as a complement to other strategies rather than a standalone fix.
Try Lymphatic Drainage Massage
Your lymphatic system collects excess fluid from tissues and returns it to your bloodstream. When this system gets sluggish or overwhelmed, fluid pools in your feet and ankles. Lymphatic drainage massage uses very light, rhythmic pressure to help move that fluid along.
A trained therapist typically starts by stimulating the lymph nodes in your groin, armpits, and neck to “open” drainage pathways. Then they use gentle, sweeping strokes to guide fluid from your swollen feet and ankles upward toward those lymph nodes, where it can be reabsorbed. The pressure is much lighter than a traditional massage. You can also learn simplified self-massage techniques: using your palms, gently stroke from your ankle toward your knee in slow, repeated motions. Always move toward the heart, not away from it.
Swelling During Pregnancy
Some degree of ankle swelling is normal during pregnancy, especially in the third trimester. The Mayo Clinic recommends several safe approaches: avoid standing for long periods, sit with your feet elevated when possible, wear compression stockings, and sleep on your left side to take pressure off the large vein that carries blood from your lower body back to your heart. Placing pillows under your legs at night can also help.
Standing or walking in a pool is particularly effective during pregnancy because the water pressure gently compresses your legs while the buoyancy takes weight off your feet. Avoid clothing with tight bands around your ankles or calves, which can restrict circulation. One important note: don’t reduce your water intake in an attempt to reduce swelling. Staying well hydrated, around 10 cups a day, actually helps your body manage fluid balance.
When Edema Points to Something Deeper
Swelling that comes and goes with long days on your feet, warm weather, or salty meals is usually benign. But edema can also signal an underlying condition that needs treatment. Venous insufficiency, where the valves in your leg veins weaken and allow blood to pool, is one of the most common causes of chronic lower-leg swelling. This type of edema typically worsens as the day goes on and improves with rest and elevation. It’s managed long-term with compression, exercise, and sometimes medications that strengthen vein walls and reduce inflammation.
Heart, kidney, and liver conditions can all cause fluid retention that shows up in the feet and ankles. When these conditions are responsible, a healthcare provider may prescribe diuretics, which are medications that help your kidneys excrete more sodium and water. These range from mild options to more powerful types depending on how much fluid needs to be removed. Diuretics treat the symptom, not the cause, so identifying and managing the underlying condition is what ultimately controls the swelling.
Warning Signs That Need Urgent Attention
Most foot and ankle swelling is manageable at home, but certain patterns require prompt medical evaluation. Swelling in only one leg, especially if it comes on suddenly with pain or warmth, could indicate a blood clot. Swelling paired with shortness of breath may point to a heart or lung problem. Other red flags include fever, severe pain, coughing or vomiting blood, and jaundice (yellowing of your skin or eyes).
Swelling that appears suddenly across multiple parts of your body, or facial swelling from an allergic reaction, is a medical emergency. If your edema is new, worsening despite home measures, or interfering with your ability to walk or wear shoes, that’s a signal to get evaluated rather than continuing to manage it on your own.
