Swollen legs and feet usually result from fluid pooling in your lower extremities, and the fastest way to start reducing that swelling is to elevate your legs above heart level for about 15 minutes, three to four times a day. But lasting relief depends on addressing why the fluid is collecting in the first place. Here’s how to tackle the swelling from multiple angles.
Elevate Your Legs the Right Way
Simply propping your feet on an ottoman isn’t enough. Your legs need to be positioned above the level of your heart so gravity can pull trapped fluid back toward your core. Lie on a bed or couch and stack pillows under your calves and ankles until your feet are higher than your chest. Hold this position for about 15 minutes, and repeat three to four times throughout the day. Many people do this once in the morning, once after lunch, once in the late afternoon, and once before bed.
If you work at a desk, even tilting your chair back and resting your feet on a raised surface during breaks helps. The key is consistency. A single session won’t make much difference, but doing it several times daily creates a noticeable reduction in swelling over the course of a few days.
Use Compression Stockings
Compression stockings apply graduated pressure to your legs, squeezing fluid upward and preventing it from settling around your ankles. They come in different pressure levels measured in mmHg, and choosing the right level matters.
- 15–20 mmHg: Good for mild, everyday heaviness and slightly swollen legs. Available over the counter.
- 20–30 mmHg: Better for noticeable swelling from mild edema. Often the most commonly recommended starting point.
- 30–40 mmHg: Designed for moderate to severe edema and lymphedema, typically requiring a prescription or fitting.
Put them on first thing in the morning before swelling has a chance to build up. If you wait until your legs are already puffy, the stockings are harder to pull on and less effective. Knee-high versions work for most people with foot and ankle swelling, while thigh-high or full-length options may be better if swelling extends above the knee.
Move Your Feet and Calves Often
Your calf muscles act as a pump for your veins, pushing blood and fluid back up toward your heart with every contraction. When you sit or stand in one position for hours, that pump stalls and fluid pools in your lower legs.
Ankle pumps are the simplest fix. Sit or lie with your legs extended, then point your toes toward your knees as far as you can, hold briefly, and point them away from you. Alternate back and forth for two to three minutes, and repeat two to three times per hour. Walking, even for five minutes every hour, activates the same calf pump more vigorously. Calf raises (standing on your toes and lowering back down) are another quick option you can do at a standing desk or while waiting in line.
Try Gentle Lymphatic Massage
Lymphatic drainage massage uses very light pressure to move trapped fluid through your lymphatic system and out of your legs. This isn’t a deep tissue massage. Firm pressure actually blocks lymph flow. You’re aiming to gently stretch the skin, not knead the muscle underneath.
Start at the top and work down, then sweep fluid upward. First, use flat hands to gently stretch the skin of your inner thigh upward toward your stomach. Then move to your knee, pulling the skin up toward your thigh. For your lower leg, place your hands around your calf and gently pull the skin upward toward the knee. Finally, for your foot and ankle, place your hands under the ankle bones and stretch the skin up toward your leg, then work from your toes toward your ankle. Each stroke should be slow and rhythmic, like you’re lightly pulling a sheet of paper across your skin. Repeat for five to ten minutes per leg.
Cut Back on Sodium
Excess sodium causes your body to hold onto water, and much of that extra fluid ends up in your legs and feet. The World Health Organization recommends staying under 2,000 mg of sodium per day, which is less than a teaspoon of table salt. Most people consume well over that amount without realizing it, largely from processed and restaurant foods.
The biggest sodium sources tend to be bread, deli meats, canned soups, frozen meals, sauces, and cheese. Swapping even a few of these for lower-sodium alternatives can make a measurable difference in swelling within a week or two. Reading nutrition labels is the most practical step: look at the sodium line and aim for items under 300–400 mg per serving. Cooking at home with fresh ingredients gives you the most control.
Stay Hydrated
It sounds counterintuitive, but drinking enough water actually helps reduce fluid retention. When you’re dehydrated, your body responds by holding onto whatever fluid it has, concentrating sodium in your blood and making swelling worse. Steady water intake throughout the day keeps sodium levels balanced and helps your kidneys flush excess fluid more efficiently. There’s no magic number, but most adults do well with six to eight glasses daily, adjusting for heat and exercise.
Check Your Medications
Several common medications cause leg and ankle swelling as a side effect. Calcium channel blockers, a widely prescribed class of blood pressure medication, are one of the most frequent culprits. The swelling they cause isn’t from your body retaining extra fluid overall. Instead, these drugs cause fluid to shift from your blood vessels into the surrounding tissue, particularly in the legs. At high doses taken long-term, the incidence of ankle swelling can exceed 80%.
Other medication classes known to cause lower leg swelling include certain diabetes drugs, some anti-inflammatory pain relievers, steroids, and hormone therapies. If your swelling started or worsened after beginning a new medication, that connection is worth raising with your prescriber. Dose adjustments or switching to an alternative often resolves the problem.
When Swelling Signals Something Serious
Most leg swelling is manageable at home, but certain patterns point to conditions that need prompt medical attention. The most important distinction is whether the swelling affects one leg or both.
Sudden swelling in one leg, especially with pain, cramping, warmth, or skin that looks red or purple, can indicate a deep vein thrombosis (DVT), a blood clot in a deep vein. DVT can sometimes occur without obvious symptoms, which makes any unexplained one-sided swelling worth getting checked. If a clot breaks loose and travels to the lungs, it becomes a pulmonary embolism. Warning signs of that include sudden shortness of breath, chest pain that worsens with deep breaths or coughing, dizziness, a rapid pulse, or coughing up blood. That’s a medical emergency.
Swelling in both legs that develops gradually and doesn’t go away with elevation can signal heart failure, kidney disease, or liver problems. In heart failure, the heart can’t pump efficiently, so fluid backs up into the legs, lungs, and abdomen. In kidney disease, the kidneys lose the ability to remove excess fluid from the body. Both conditions produce persistent swelling that worsens over time, often accompanied by other symptoms like fatigue, shortness of breath when lying flat, or changes in urination. New or worsening bilateral swelling that doesn’t respond to the strategies above warrants a medical evaluation.
