Swollen Ankles Symptoms

As the day wears on, your feet start to throb and your shoes feel tighter. When you finally get to rest your feet and peel off those socks and shoes, you notice it has happened again. Swollen ankles can be unsightly and uncomfortable. The swelling can be a sign of a problem with the ankle itself or a more serious medical condition.

The ankle swelling may be associated with:

Swollen Ankles Causes Overview

Swelling in the body is usually a sign of an underlying problem. Sometimes swelling in a sign of inflammation in the affected area, after an injury, for instance. Inflammation is more likely to affect one area or one side of the body. Swelling can also be caused by problems with fluid balance. When the body holds on to too much fluid, it collects in the legs and ankles due to gravity. This is more likely to affect both sides of the body equally. Some common causes of swollen ankles, divided by category, are outlined below.

Fluid problems

  • Vein issues: Your veins drain blood from the ankles and transport it back to the heart. As we age, problems can develop with this system and fluid can build up.
  • Heart disease: When your heart struggles to pump blood (heart failure), the body holds on to extra fluid that can buildup in your ankles and other areas.
  • Liver disease : A damaged or diseased liver, such as cirrhosis or severe hepatitis, can cause fluid retention or leakage into certain areas of the body.
  • Kidney disease: Your kidneys do the complex job of keeping salt, fluid and electrolytes in balance.

Physical causes:

  • Overuse: Walking all day or exercising more than usual puts strain on the ankles that may lead to temporary inflammation and swelling.
  • Trauma : Swelling may be the most obvious sign of a broken or sprained ankle that may also be painful.
  • Sitting still: Remaining seating for long periods of time, such as during an airplane ride, allows blood and fluid to pool in the ankles due to the force of gravity.

Other medical causes:

  • Pregnancy: Hormones and other effects of pregnancy make the body hold on to more fluid and reduce venous return from the lower extremities and increase the amount of fluid that collects in areas like the ankles.
  • Autoimmune problems: Certain diseases like lupus increase inflammation throughout the body and may lead to ankle swelling.
  • Blood clot: A blockage in your vein (deep vein thrombosis or DVT) prevents blood from draining from the ankle and may travel to arteries in your lungs if not treated appropriate.
  • Infection: Bacteria can invade the skin around the ankles or the ankle joint itself, leading to swelling that is usually also accompanied by warmth and redness.
  • Medications: Certain pills, such as some kinds of blood pressure medications, make it more likely that fluid will pool in your legs and ankles. Your doctor or pharmacist can tell you the side effects of the medicines you take on a regular basis.

  1. 1.Charcot Arthropathy of the Ankle

    Charcot Arthropathy of the foot is a syndrome where patients with numbness of their feet, which can be caused by a variety of underlying conditions such as diabetes, develop weakening of the bones in the foot and ankle. Thus they may have fractures and dislocations of the bones and joints that occur with little trauma.

    Healing may require several months.

    Rarity:
    Rare
    Top Symptoms:
    joint pain, constant ankle swelling, pain in one ankle, swollen ankle, painful ankle swelling
    Symptoms that always occur with charcot arthropathy of the ankle:
    warm red ankle swelling, constant ankle swelling
    Urgency:
    Primary care doctor
  2. 2.Nephrotic Syndrome

    Nephrotic syndrome is caused by different disorders that damage the kidneys. This damage leads to the release of too much protein in the urine, causing the body to swell.

    Varies by cause of Nephrotic Syndrome

    Rarity:
    Rare
    Top Symptoms:
    fatigue, loss of appetite, shortness of breath, weight gain, bilateral leg swelling
    Symptoms that never occur with nephrotic syndrome:
    cut on the foot, recent cut or wound, swollen ankle, swelling of one leg
    Urgency:
    Primary care doctor
  3. 3.Restrictive Cardiomyopathy

    Restrictive cardiomyopathy refers to a set of changes in how the heart muscle functions. These changes cause the heart to fill poorly (more common) or squeeze poorly (less common). Sometimes, both problems are present.

    Indefinite

    Rarity:
    Rare
    Top Symptoms:
    fatigue, shortness of breath, chest pain, racing heart beat, shortness of breath when lying down
    Urgency:
    Hospital emergency room
  4. 4.Third Degree Atrioventricular Nodal Block

    3rd degree atrioventricular nodal block is the most severe form of conduction blockage.

    Indefinite

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, tight, heavy, squeezing chest pain, lightheadedness, deep chest pain, behind the breast bone
    Symptoms that never occur with third degree atrioventricular nodal block:

  5. 5.Stress - Induced Cardiomyopathy

    In this recently recognized heart problem, extreme emotional stress can lead to severe (but often short-term) heart muscle failure. Broken heart syndrome is also called stress-induced cardiomyopathy.

    Most patients make full recovery within one to two months.

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, muscle aches, deep chest pain, behind the breast bone, excessive sweating
    Urgency:
    Primary care doctor
  6. 6.Ebstein Anomaly of the Tricuspid Valve

    Many heart conditions are present from birth (congenital), and some can cause the valves to function improperly, resulting in symptoms such as poor blood circulation, fatigue, and difficulty breathing.

    Prognosis depends heavily on severity of the heart condition

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, severe fatigue, lightheadedness, deep chest pain, behind the breast bone
    Urgency:
    Primary care doctor
  7. 7.Eisenmenger Syndrome (Tardive Cyanosis)

    Eisenmenger syndrome is a complication due to a heart defect. The defect causes increased blood flow to the lungs instead of the body.

    This condition is considered irreversible, but heart transplantation is an option for some patients.

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, shortness of breath on exertion, shortness of breath when lying down, decreased exercise tolerance
    Urgency:
    Primary care doctor
  8. 8.Goodpasture Syndrome

    Goodpasture syndrome is an autoimmune disorder, which means immune system mistakenly attacks and destroys healthy body tissue. Persons with this syndrome develop substances that attack a protein called collagen in the tiny air sacs in the lungs and the filtering units (glomeruli) of the kidneys.

    Autoimmune disorders of this type are considered irreversible, but symptoms can be effectively managed with treatment.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, nausea, shortness of breath, muscle aches, fever
    Urgency:
    Primary care doctor
  9. 9.Cushing Syndrome

    Cushing Syndrome is a hormonal disorder. The cause is long-term exposure to too much cortisol, a hormone that the adrenal gland makes. Sometimes, taking synthetic hormone medicine like corticosteroids to treat an inflammatory disease leads to Cushing's syndrome.

    Recovery depends on treatment method

    Rarity:
    Rare
    Top Symptoms:
    fatigue, headache, depressed mood, weight gain, back pain

Swollen Ankles Treatments and Relief

If you have some occasional swelling, the good news is that there are several swollen ankle treatments you can try in the comfort of your own home. These common-sense measures can reduce discomfort and get you back on your feet. If the swelling persists for a long period of time or becomes particularly severe or bothersome, then visit your doctor as medications and tests may be in order.

At-home swollen ankle treatments:

  • Get moving: If you've been sitting still, get up and use those legs. The contraction of the leg muscles helps push fluid back into the veins and out of your ankles.
  • Rest: On the other hand, if you've been on your feet or have injured your ankle, it's best to take it easy for a few days.
  • Ice: Cold temperatures constrict blood vessels, reduce swelling and can help with discomfort.
  • Elevation : Keep those legs up on a chair or ottoman to counteract the effect of gravity, which naturally pulls fluid down into your ankles.
  • Compression stockings : These tight socks can be worn for several hours to help reduce ankle swelling.

Professional swollen ankle treatments:

  • Detailed physical examination: Your doctor will examine the area of swelling but will also look for signs of problems with your heart, kidneys, and liver as these can lead to swelling throughout the body.
  • Medication: Certain drugs, such as water pills or diuretics, help the body remove excess fluid in a natural way. Other medicines can treat underlying medical conditions that lead to ankle swelling.
  • Blood tests: These can inform your doctor if your organs are functioning properly and if your medications are having the desired effect.
  • Imaging: An ultrasound or other type of image may be taken of the area of swelling to look for problems like blood clots. (DVT).

Seek help without delay if you have:

  • Severe shortness of breath
  • Severe pain, including chest pain
  • Redness or warmth over the ankle joint
  • Swelling in one leg after sitting still for a prolonged time, such as during plane travel

FAQs About Swollen Ankles

Here are some frequently asked questions about swollen ankles.

Why do my ankles swell after a flight?

Ankles swell after a flight because fluid collects in the legs over the duration of the flight. This is partially because of increasingly tight seating arrangements on planes, the long duration during which passengers do not rise and walk during travel, and the negative pressure that your body experiences during the flight. If your ankles tend to swell to the point of discomfort, you can wear compression socks.

Do certain medications cause ankle swelling?

Many medications can cause fluid retention. Once your body begins to retain fluid, the fluid settles in the lowest area of your body — your ankles. Medications that can cause ankle swelling include oral or topical steroids, NSAIDS or non-steroidal anti-inflammatory drugs like ibuprofen, several diabetes medications, antidepressant medications, and certain blood pressure and heart medications called calcium channel blockers.

Why do my ankles swell after giving birth?

After giving birth, the blood that was going to the baby and the placenta (the organ that keeps the baby alive) re-enters your bloodstream. You have a little more blood than you did before you became pregnant. This is generally a good thing. However, this blood can cause extra fluid to pool in your legs until it is reabsorbed into your body.

When should you seek medical attention for swollen ankles?

You should seek medical attention first if you see any changes in your skin. If you have a non-healing cut, a blue or darkening of the skin of one or both legs, or even a loss of hair along the legs, you should seek medical attention. Second, if one leg is more swollen than the other, you should seek medical attention. This can be a sign of a blood clot (deep vein thrombosis or DVT), and if left untreated can travel to the lung and may be life-threatening. Finally, if you experience pain or a decrease in sensation of either one or both legs you should seek medical attention. This may be a sign of diabetes, severe edema, or a lack of blood flow to the lower extremity — all of which require medical treatment. If one leg feels cold, seek emergency medical treatment immediately.

Can swollen ankles be a sign of menopause?

Yes, swollen ankles can be a sign of menopause. As the hormones of the body change, the fluid balance of the body also changes, and fluid can pool in many areas. When it pools in the tissues of the abdomen one can feel bloated, and one can also experience leg swelling during menopause.
