Swollen feet can be normal, but they can also be a warning for heart, liver, or kidney disease. Find out what to do for swollen feet and when to call your doctor.

Sometimes what to do about a swollen foot is an easy call. If you sprain your ankle or your foot is suddenly painful and swollen, calling your doctor is the way to go. [1] But what if you look down at your feet and ankles at the end of the day and they just look puffy and swollen?

Painless swelling that occurs in both feet and ankles is what doctors call peripheral edema. It happens when the tiniest blood vessels in your legs—your capillaries—leak fluid into your tissues and the fluid pools down in your feet and ankles. Another name for this edema is fluid retention. [1-4]

It is common to have more edema in hot weather or after a long trip. In most cases, this edema is not dangerous and you can treat it on your own. [4] However, in some cases it can be caused by a serious disease. [1,3] So how do you know the difference?

Normal Swelling in Your Feet

It’s normal to have some swelling if you have been sitting or standing for long periods. You could be at higher risk for normal swelling if you are pregnant or you have been eating too much salty food. Some medications also cause edema, including blood pressure medications, nonsteroidal anti-inflammatory drugs (like Advil and Motrin), and steroid drugs. [2,4]

Here are some things to do for swollen feet at home:

  • Decrease your salt intake
  • Drink more fluids, about 10 glasses of water per day to get fluids moving out through your urine
  • Lose weight if you are overweight
  • Prop your legs up when you are sitting and prop them up on a pillow in bed
  • Avoid long periods of sitting or standing. Get up and do some walking
  • Try soaking your feet in water with Epsom salt, 15 to 20 minutes in cool water
  • Wear compression socks or stocking during the day. Make sure they are snug but not too tight
  • Try taking a magnesium supplement. Two to four hundred milligrams of magnesium may help reduce fluid retention [2,4]

If these home remedies don’t help, talk to your doctor. Ask your doctor if there are any medications that could be causing fluid retention. Your doctor may do some tests to see if there are any medical reasons for your fluid retention. [2,4]

Serious Causes of Foot Swelling

Although less common, there are many causes of fluid retention or swelling that can be serious. They include:

  • Heart disease and heart failure
  • Kidney disease
  • Liver disease
  • A blood clot that forms in your leg, called thrombophlebitis
  • Blocked lymph vessels, called lymphedema
  • Weak leg veins that are unable to return blood to your heart, called venous insufficiency [1,3]

Call your doctor if:

  • Swelling is only on one side or swelling is painful
  • The skin over your feet or ankles is stretched and shiny
  • Pressing a finger into the swelling leaves a dimple (called pitting edema)
  • You feel short of breath or lightheaded

Get immediate medical care if:

  • You’re experiencing pain, swelling, warmth, and tenderness in your calf area
  • You have difficulty breathing
  • You have chest pain [1,3]

The Bottom Line on Swollen Feet

Some fluid retention that seeps down into your feet and ankles is common and not serious. In most cases, this type of swelling goes away as soon as you prop your legs up. Let you doctor know if you have swelling that is frequent, painful, severe, or does not go away with home care. [1-4]

  • I have had swelling of my feet and ankles for over a year now. I hurt when walking, so much I want to cry. My shoes will not go on my feet at all sometimes. My hands will swell at times as well. Doctors have gone through my medications and I have had a few tests done. Still they haven’t been able to help me. What can I do?????

    • Hi Dawn, thank you for your comment. Unfortunately, we’re unable to offer personalized medical advice, so it’s best to speak with a medical professional. Thank you reading and we hope you feel better soon!

  • I had swollen feet a few months back and without me noticing after my feet were back to normal that I had some brucing and it is still there
    we re..

  • So my bf has hand swollen feet ankles and hands off and on for the last five years. And the few years its gotten worse. Now his hes got liaisons on his red swollen feet . compression socks dont help either and now hes feeling sharp stabbing pains in his feet. And he wont go to the doctor. What can I do to help.

  • Both of my feet have been swollen for 2 days now.i don’t even fit in any of my shoes.when I push on top of my swollen foot it leaves a big indent.very uncomfortable nothing refuses the swelling.

  • Wow, I never thought that swollen feet can be an indicator of a life-threatening condition. I think I will ask my sister to go to a foot doctor because the swelling has been ongoing for 3 days already. I’m pretty sure it’s starting to spread up to her legs so she may have to see a professional as soon as possible.

  • Well explained about swollen feet and their conditions. Also clearly said about which diseases are associated with this. And What are the problems we have to face. Thank you.

  • I am being treated for edema of the feet extending up to the calves. There is a possibility that a BP med I was recently put on could be the cause since swelling of legs and feet was one of the first side effects listed. My blood tests came back normal for the kidneys and liver. My blood sugar is a little high but not enough to warrant medication. The previous BP med I was on for a few months (following a TIA) could have been the culprit behind unrelenting eyelid twitches and that is why my BP was changed. The twitches eventually subsided. I’m on a salt restrictive diet now. I am exercising 30 minutes to 1 hour per day usually in the form of a brisk walk. My legs and feet went back to normal 2 days after the change in BP med and after drastically reducing salt. My heart “seems” to be normal and I have had many tests done in that department since October of 2018 when I had my first TIA. I realize that things can change over time but my doc is not ordering test of my heart as-of yet. He was hoping that the change in BP med and lifestyle changes might be what is needed in my case. So far, and it’s been a week now, my feet, ankles and calves are normal sized and there is no tightness. I can push on the flesh and there is no pitting like before. I am hoping that there is nothing serious going on and that by eating less and eating better, exercise and losing some weight (I need to lose about 35 lbs) I can turn my health around!

  • My feet are swollen and it feels like a knife is going through them and it hurts just to touch them a little is this a bad sign
