Peripheral edema or swelling of the foot is caused by all the underlying factors that cause ankles and legs to swell from the pooling of blood or fluid in the foot area. Show Swelling in the feet can result from:
The swelling can result from fluid retention or poor circulation because of damage to the blood vessels or other factors. Edema: Excess Fluid Trapped in Tissues The tissues directly under the skin look puffy and swollen. The skin may look stretched and shiny, and when you press on it, a dimple remains. Swollen feet make it difficult for you to walk. If you are standing all day, then your feet naturally swell - when buying shoes, it is suggested that you try them on later in the day because this swelling increases your shoe size. Most edema goes away when you take the weight of your feet. If you regularly get swollen feet, you can try:
Pregnancy Pregnancy brings extra weight and the pressure of supporting a growing baby. Most women suffer from swollen feet during pregnancy at some stage. In addition to the treatment for edema, you can:
Alcohol Alcohol, along with other health impacts, can result in swollen feet because of fluid retention. Frequent swelling in the feet after drinking alcohol may indicate problems with your organs - heart, liver, or kidneys. It may also mean your alcohol consumption is excessive and problematic. To reduce alcohol-related foot swelling, drink more, and consume less salt. You can also try soaking your feet in cold water. Hot Feet In hot weather or anything else that causes your feet to get hot, your feet may swell. The veins expand to try to cool you down, and this can result in fluid in nearby tissue or pooling if you have poor circulation. Cooling and exercising your feet help to alleviate the symptoms and reduce swelling. Lymphedema Damage or removal of your lymph nodes (some cancer treatment) causes your body to retain lymphatic fluid. Your feet are the lowest part of your body and can swell as a result. Other symptoms include:
There is no cure for lymphedema because you can reverse the damage or put back the lymph nodes. The best you can do is manage the condition with pain relief and action to reduce the swelling in your feet. Actions you can take include:
Chronic Venous Insufficiency In Chronic Venous Insufficiency the valves in your veins can become damaged from prolonged sitting and standing. If they don't work as well as they should, your blood circulation suffers, and pooling blood leads to swelling. As well as the swelling, you may see flakey, itchy skin, and ulcers. Early diagnosis leads to better outcomes. Treatment usually involves changes in how you treat your feet:
Kidney Disease Along with other problems, the retention of water can result in swelling in your feet. Your doctor will advise on medication and dietary changes to treat the kidney disease. If you manage your kidney disease, you will have fewer problems with your feet. Liver Disease Problems with your liver result in fluid retention and foot swelling. You can damage your liver by substance abuse, obesity, viruses, and some genetic causes. If you treat your liver disease, you reduce the swelling in your feet. Blood Clots Deep Vein Thrombosis occurs when a clot forms that blocks normal blood flow in the deep veins. Blood clots are solid masses of blood that can form in your veins and impeded blood flow. If the swelling in the foot is the result of a blood clot, you expect only one foot to be impacted, depending on where the clot forms. You may also feel pain or tenderness and see a reddening of the skin. If you are at risk of blood clots, your doctor will advise preventive measures like:
Infections Your feet can become infected and inflamed from injury or with a nerve condition like diabetic neuropathy leaving your feet more infection-prone. Most infections are treatable with antibiotics taken orally or applied to the infection site. MedicationSome medications result in fluid collecting in and swelling your feet. Some of the medicines most likely to cause swelling in your feet as a side effect are:
Antidepressants It's best to discuss your swollen feet with your doctor who can advise changes to your dosage, other medication, or perhaps the use of a diuretic to deal with the excess fluid as appropriate. Heart Failure Most people expect chest pain as a sign of heart failure. Many symptoms result from your heart failing to pump blood the way it should - swollen feet are one of them. Immediate medical attention is essential in heart failure, and you will need to manage your condition for the rest of your life. You have a range of treatment options from medicine, surgery, and inserting medical devices like pacemakers and replacement valves.

Medically reviewed by Meredith Goodwin, MD, FAAFP — By Rachel Nall, MSN, CRNA and Emily Cronkleton — Updated on August 15, 2022 The feet, ankles, and legs are common sites of swelling because of gravity’s effect on the fluids in the human body. However, fluid retention from gravity isn’t the only cause of a swollen ankle or leg. Injuries and subsequent inflammation can also cause fluid retention and swelling. A swollen foot, ankle, or leg can cause the lower part of the leg to appear larger than normal. The swelling can make it difficult to walk. It may be painful, with the skin over your leg feeling tight and stretched out. This swelling is usually temporary and not cause for concern. But you’ll still want to take measures to reduce swelling. This way, you can reduce any pain you’re experiencing and resume your daily activities. If parts of your lower leg remain swollen or you have other symptoms, it could signal that you have an underlying health condition. Knowing the cause of your swelling can help rule out a more serious problem. Continue reading to learn possible causes of a swollen foot, ankle, or leg, and what you can do to reduce swelling. When is it an emergency? Swelling in the lower leg is typically the result of one of two things:
Edema is a common condition where excess fluid is trapped in your body’s tissues. This causes swelling and puffiness of the tissue directly under your skin in your feet, ankles, and legs. It can also affect your hands and arms. Other symptoms of edema include stretched or shiny skin, or difficulty walking. Some people may also experience pitting edema, in which the skin retains a dimple after you press on it for several seconds. Later on, we’ll review health conditions that can cause edema, but some causes are just everyday activities or life factors, such as:
Inflammation is your immune system’s response to injury, infection, or disease. It can be acute (short-term) or chronic (long-term). Swelling from inflammation is usually accompanied by:
Now let’s look at some specific causes of edema or inflammation in your lower leg. Swollen ankles and legs are common when you’re pregnant because of factors such as:
You may be more prone to swollen feet in the evening and especially after being on your feet all day. Swollen feet and ankles may become particularly noticeable in the fifth month. The swelling tends to go away after you deliver your baby. Until then, try these tips to prevent or lessen the swelling. Don’t reduce your water intake if you have swelling. You need plenty of fluids during pregnancy, usually at least 10 cups per day. If the swelling is painful, you should see your doctor to make sure that your blood pressure is normal. Your doctor will also want to check if you have a blood clot and rule out other possible conditions, such as preeclampsia. PreeclampsiaSudden or excessive swelling in your ankles, hands, and face could be a sign of preeclampsia. This is a serious condition where you develop high blood pressure and protein in the urine. It usually happens after the 20th week of pregnancy. People with preeclampsia may also have: Contact your doctor right away if you experience sudden swelling, especially if it’s accompanied by these other symptoms. Preeclampsia warning signs Swelling in the foot, ankle, or leg could be the result of inflammation due to acute, or even chronic, injury. When you hurt your lower leg, swelling occurs as a result of blood rushing to the affected area. Conditions that can cause this type of inflammation include: The R.I.C.E. approach is often recommended to treat leg and foot injuries. This method involves:
While resting the leg or foot is important, too much rest can lead to problems with circulation. Check with your doctor about the appropriate amount of activity for your leg. Depending on the severity of your injury, your doctor may recommend an over-the-counter (OTC) or prescription pain reliever. You may need to wear a brace or splint. Severe cases may require surgery. You should see a doctor if your pain is severe or you’re unable to put any weight on or move your foot. Also seek medical care if you’re experiencing numbness. Your swollen foot, ankle, or leg may be due to an underlying chronic condition. It might also be due to medications that you’re taking or as an after-effect of surgery. Here are some of the possible underlying conditions that may cause your foot, ankle, or leg to swell. Blood clotBlood clots are solid clumps of blood. They can form deep in the veins of your legs, a condition known as deep vein thrombosis. Blood clots hamper blood flow up to your heart and lead to swollen legs, feet, or ankles. The swelling often occurs on one side of your body. Swelling may be accompanied by other symptoms such as:
A blood clot is a medical emergency. Seek care immediately if you have these symptoms. Treatment options and preventive measures include:
BursitisBursitis is when fluid-filled sacs around your joints (called bursae) become inflamed. This causes swelling and pain at the joint. It’s common in older adults and people who repetitively use specific joints, like athletes or people in certain jobs. Bursitis can develop at any joint where there is a bursa. In the leg, it’s most common at the knee and ankle. In addition to pain and swelling, symptoms include:
Pain relief medications along with rest and ice may help to manage the condition. In more severe cases, corticosteroids may be needed. If the bursa becomes infected, you may need antibiotics. CellulitisCellulitis is a bacterial infection that occurs beneath the skin, causing pain, discoloration, and swelling. Cellulitis may be life-threatening if left untreated. Symptoms of cellulitis include:
You may experience fever with cellulitis, but not always. The area is red and expanding. Often the edge of the redness can be felt under the skin, as though there is a piece of cardboard under the skin. If you experience signs of cellulitis, get medical treatment immediately. Cellulitis is treated with antibiotics. It should go away after 7-10 days of treatment. Chronic venous insufficiencyChronic venous insufficiency is caused by damaged valves in the veins combined with standing or sitting for extended periods. This affects blood moving up to your heart from your legs and feet. Blood can collect in the veins of your legs and feet, causing swelling. You may experience the following symptoms: See a doctor if you have signs of venous insufficiency. It’s easier to treat the earlier it’s diagnosed. Treatments include:
DiabetesDiabetes affects your ability to control sugar levels in your blood. High blood sugar levels can damage blood vessels which leads to poor blood circulation. This can cause blood to settle in your lower leg, causing swelling. Prolonged circulation problems may eventually lead to nerve damage in your foot, which could also make it more susceptible to injury which can lead to swelling.. To help with swelling caused by diabetes, your doctor may recommend:
Nerve damage in your foot can also cause Charcot foot, an inflammatory condition that affects bones and tissue in the foot. In addition to swelling and numbness, Charcot foot is characterized by:
Charcot foot is a serious condition that could require amputation if not treated. GoutA buildup of uric acid in your blood is called gout. As an acute condition, it can cause swelling in affected joints. This often affects the feet, particularly the big toe. Gout flares usually last for 3 to 10 days. But if left untreated, gout can become chronic, leaving lumps called tophi in your joints and tissue. Tophi can cause permanent damage to your joints. Associated symptoms of gout include:
There are medications you can take to prevent gout flare-ups. You can also take NSAIDs or corticosteroids to relieve the pain. Home remedies such as apple cider vinegar and black cherry juice may help with symptoms. But consult a doctor if your symptoms are severe or come on suddenly. Heart failureIn right-sided heart failure, the heart’s right ventricle is too weak to pump enough blood to the lungs. As blood builds up in the veins, fluid gets pushed out into the tissues in the body. This could be brought on by a heart attack, valve disorders, or lung diseases like chronic obstructive pulmonary disease (COPD). Right-sided heart failure symptoms include swelling and shortness of breath. You may also experience: Get immediate medical treatment if you’re experiencing these symptoms. Heart failure needs lifelong management. Treatment options include medications, surgery, and medical devices. InfectionSwollen feet and ankles may be caused by infections and the accompanying inflammation. People with diabetic neuropathy or other nerve conditions of the feet are more prone to foot infections. Infections can be caused by wounds such as blisters, burns, and insect bites. You may also experience: If you have a bacterial infection, you may need prescription oral or topical antibiotics to treat it. Kidney diseaseIf you have kidney disease or your kidneys aren’t working properly, you may have too much salt in your blood. This causes your body to retain water, which can lead to swelling in your feet and ankles. The following symptoms may also be present: Treatment options include: Ultimately, kidney failure may be treated with a kidney transplant or dialysis. Liver diseaseLiver disease can cause foot and ankle swelling due to the liver not functioning properly. This leads to excess fluid in your legs and feet, which causes swelling. Liver disease can be caused by genetic factors. Viruses, alcohol, and obesity are also linked to liver damage. Other symptoms include: Treatment options include:
LymphedemaLymphedema occurs as a result of lymph nodes that are damaged or removed, often as part of cancer treatment. This causes your body to retain lymphatic fluid and can lead to swollen feet and ankles. Other symptoms may include: You can’t cure lymphedema, but you can manage the condition by reducing pain and swelling. Severe lymphedema may require surgery. Treatment options include:
Popliteal cystSynovial fluid reduces friction in your joints so you can move them more easily. But a buildup of too much synovial fluid in your knee can cause a popliteal cyst (or Baker’s cyst) to form. It’s usually the result of injury or arthritis. The cyst appears as a large bump behind the knee. Other symptoms that may go along with it include:
You can relieve pain from the cyst with steroids like cortisone. Your doctor can even drain the cyst, but that doesn’t mean it won’t return. The most important thing to do is to identify and treat the underlying cause of the cyst. Rheumatoid arthritisRheumatoid arthritis (RA) is an autoimmune condition that affects the lining of your joints. Fluid builds up around your joints, causing swelling and potentially permanent damage. Along with swelling, you may experience:
If you experience swelling due to RA, your doctor may recommend: SurgerySwelling is common after surgery. The early stages of healing usually involve inflammation, which can cause moderate to severe swelling. Mild to moderate swelling may persist for up to 6 months depending on the type of surgery you had. Reduce post-operative swelling by:
If your swelling goes on for too long or gets more severe, talk to your doctor. This could be a sign of an infection or blood clot. MedicationsSome medications cause fluid to collect, especially in the lower part of your body. These include: If you suspect that your medications are causing swollen feet and ankles, it’s important to see a doctor. Together, you can determine whether there are other options in terms of medications or dosages. They may prescribe a diuretic to help reduce excess fluid. Drinking alcohol can lead to swollen feet and ankles since your body retains more water after drinking. Usually, it’ll go away within a few days. If the swelling doesn’t subside during this time, it could be cause for concern. If swelling frequently occurs in your feet and ankles when you drink alcohol, it may be a sign of a problem with your liver, heart, or kidneys. This could also be a sign that you’re consuming too much alcohol. To treat swollen feet and ankles due to alcohol consumption, try these tips: Hot weatherSwollen feet and ankles frequently occur during hot weather since your veins expand as part of your body’s natural cooling process. Fluids, including blood, go into nearby tissues as part of this process. However, sometimes your veins aren’t able to bring blood back to the heart. This results in fluid collecting in the feet and ankles. People with circulatory problems are especially prone to this. Here are some home remedies to reduce swelling during hot weather:
In many cases, you can treat a swollen foot, ankle, or leg at home. Home management will depend on the cause. If your swelling is the result of fluid buildup, the following home tips may help relieve swelling: If your swelling is due to injury, remember R.I.C.E. but consult with a doctor regarding how much activity your leg should get. If you have a medical condition that can lead to swelling, take your medications and manage your symptoms carefully. If you have congestive heart failure or kidney disease, you may need to limit the amount of fluid you take in each day. Exercise precautionsWhile you can’t always prevent injuries during physical activity, warming up first can help. This includes a walk or light jog before engaging in vigorous physical activity. Choose supportive footwear. Proper shoes can help correct gait issues and prevent injuries. You should choose shoes that match your activity or your specific needs. If you jog or run, get fitted by a professional for the correct shoe. Compression socksCompression socks apply pressure to your lower leg. In some cases, this can help prevent and alleviate ankle and foot swelling caused by certain conditions, such as:
Check with your doctor before using compression socks for your swelling, because these special socks should be properly fitted for you and your needs. Wear them during the day and remove them before you go to bed. DietA low-sodium diet discourages fluid retention. Fast food often contains large amounts of sodium which can contribute to retaining fluids. Many frozen meals and canned soups often contain excess sodium, so read food labels carefully. Leg elevationIf you stand a lot during the day, try wearing compression stockings at work and propping your feet up or soaking them in water when you get home to help prevent swelling. There are many reasons for a swollen foot, ankle, or leg. It’s usually the result of fluid buildup or your body’s response to an injury or infection. Sometimes, it can be a sign of a serious condition that requires medical attention. A doctor can run tests to determine a diagnosis and treatment plan.
