Have you ever heard of something called 'Trench Foot'? This name may be new to you. But it's a condition that can affect our feet and requires some attention. It's especially important to be aware of it if your feet are exposed to moisture and cold for long periods of time. Let's take a look at what 'Trench Foot' is, why it happens, and how to avoid it.
What is Trench Foot? Simply put...
Simply put, 'Trench Foot' is a condition that occurs when your feet are trapped inside wet socks or shoes for a long time, even days, and are exposed to the cold. Some people also call this 'Immersion Foot Syndrome'. Just think, if we constantly stay in a wet, cold, and possibly dirty environment, the skin and tissues of our feet begin to be damaged.
This is a type of non-freezing cold injury . This means that the temperature does not have to be as low as freezing to cause this condition, but it can occur at temperatures slightly above freezing. Other conditions include `(Chilblains)` (which look like blisters), `(Frostnip)` (freezing of the skin), and `(Raynaud's phenomenon)` (a condition in which the blood vessels constrict and the fingers turn pale). If the skin and tissues break down due to 'trench foot', there is a high risk of infection . This can be very painful, but the good news is that it can be treated and prevented .
Why was this called 'Trench Foot'?
The name 'trench foot' comes from a somewhat old story. The condition was first described in 1812 by a French military surgeon treating soldiers in Napoleon's army. But it became world-famous during the First World War. At that time, soldiers had to stay in water-filled, muddy trenches for days, sometimes weeks. The cold, dampness, and dirt caused a large number of soldiers to develop this disease. Between 1914 and 1915 alone, more than 20,000 British soldiers were treated for 'trench foot'. Fortunately, there are better ways to prevent and treat it today. However, the condition still occurs occasionally .
Who is most likely to develop 'trench foot'?
The condition known as 'trench foot' is most commonly seen in those in the military, during their training and combat operations. However, it can also affect people in other categories. For example:
- For the homeless: They often have to wear the same pair of socks and shoes. They are exposed to the humidity and cold for long periods of time because they do not have a proper place to stay.
- For those who go to music concerts: This is also possible for those who go to large music concerts that are held outdoors for days and are exposed to cold, wet, and possibly dirty places.
- People who work around water: Fishermen, port workers, or others who spend long periods of time in water due to their jobs can also develop 'trench foot'. Even in our country, those who work in the fields during the rainy season, or those who spend long periods of time in water during flood-like conditions, also need to be careful about this, especially if the environment is cold.
- For those who engage in outdoor activities: Those who have hobbies like mountain climbing and jungle trekking can be susceptible to this condition if they do not change their wet socks and shoes in time. It is good to keep this in mind when engaging in such activities in the mountainous areas of Sri Lanka (like Nuwara Eliya, Haputale) and if the environment is cold and wet.
What are the symptoms of 'trench foot'?
As trench foot becomes more severe, the way it looks and feels changes.
At first, you may feel your feet numb, tingling, or completely numb . Some people may feel like something is being pushed into their feet, or their feet may feel very heavy, like a log. This can make it difficult for you to walk. At first, your feet may be bright red . But over time, as the blood vessels constrict, your feet will become pale, clammy, and white .
Once you get out of the cold, the skin on your feet will start to change color again. If you have fair skin, your feet may turn blue or purple due to decreased blood flow . If you have darker skin, this color change may not be as noticeable. The skin may also become cold and blotchy in places . In addition, there may be swelling . In some severe cases, your feet may even double in size!
As your feet warm up again, they may turn bright red again . You may feel intense pain or unusual sensations as blood returns to your feet. You may also develop blisters, sores, or open sores on your feet. These can make you more susceptible to fungal and bacterial infections. Your skin may become very sensitive to changes in temperature or even just a touch.
What causes trench foot?
Trench foot develops when your feet are exposed to cold, wet conditions for a long time. Remember, the temperature doesn't have to be freezing cold. Trench foot can develop even at temperatures as low as 16 degrees Celsius (60 degrees Fahrenheit) .
When cold temperatures and humidity combine, the tiny blood vessels (capillaries) in your feet begin to weaken . This can damage the surrounding tissues. Additionally, the restricted blood flow can affect your circulation and nerve function.
Having excessively sweaty feet (Hyperhidrosis) can also be a cause of 'trench feet'.
How long does it usually take for trench foot to develop?
In most cases, trench foot requires one to three days of exposure to cold, damp conditions. However, sometimes the condition can develop in as little as 10 to 14 hours . So it's important to be vigilant.
How does a doctor recognize this as 'trench foot'?
Your doctor will first perform a physical examination to diagnose trench foot. He or she will examine your feet and ask about your symptoms. He or she will also ask about your recent environment. If you have been exposed to cold, damp conditions for even a few hours, your doctor may suspect trench foot.
Your doctor will want to make sure your symptoms are not caused by an infection or another condition, such as frostbite. He or she may order a white blood cell count or ESR (Erythrocyte Sedimentation Rate) test. The ESR test checks for inflammation in your body. You may also be asked to take an X-ray or bone scan if they suspect you have a bone infection (osteomyelitis).
Is there a treatment for 'trench foot'? Can it be cured?
Yes, absolutely! Trench foot can be completely cured if diagnosed early . Treatment for trench foot includes:
- Gentle rewarming of the feet: If you warm them up too quickly, it can cause severe pain and swelling. Therefore, you should warm them up slowly.
- Keeping your feet clean, dry, and warm: Your doctor will advise you to clean your feet and keep them dry and warm.
- Resting and keeping your feet higher than your heart: This helps prevent new sores and blisters from forming.
- Antibiotics: The doctor may prescribe antibiotics to prevent infection.
- A tetanus booster shot: This will also be given if necessary.
- Painkillers: You can take painkillers like `(NSAIDs)` (non-steroidal anti-inflammatory drugs) or `(Acetaminophen)` (paracetamol). However, sometimes the doctor may also prescribe a medicine called `(Amitriptyline)`.
How do I take care of myself after treatment?
After you've been treated for trench foot, there are a few things you need to do to make sure your feet continue to heal. These are:
- Wear a clean, dry pair of socks every day.
- Don't wear socks when you sleep. That way you can keep your feet dry.
- Check your feet every day.Watch for signs of worsening symptoms or any signs of infection.
- Avoid smoking and using other products that contain nicotine. Nicotine can reduce blood flow to your feet.
- Eat a diet rich in protein. This will help the healing process.
How to prevent the development of 'trench foot'?
Trench foot is actually a condition that can be prevented . The following precautions can help you avoid developing this condition:
- Change wet socks and shoes/boots as soon as possible.
- Dry your feet by exposing them to air. Make sure to keep your feet dry at all times.

What happens if you develop 'trench foot'? Is it something to be afraid of?
In the past, trench foot was a serious condition that could even lead to death. However, today, if diagnosed and treated early, most cases of trench foot can be completely cured . You can expect to make a full recovery from this condition. However, there may be some pain for a while while full sensation in the foot is restored.
Can 'trench foot' cause dangerous complications?
Yes, if left untreated, serious complications can occur. Conditions such as `(Cellulitis)` (a bacterial infection of the skin) or `(Gangrene)` (death of tissue) can occur. In severe cases, amputation of a part of the leg may be necessary to prevent the `(Gangrene)` condition from spreading further. Other complications include `(Sepsis)` (blood poisoning) and even death.
'Trench foot' is a painful condition that got its name from the trenches soldiers had to endure during World War I. Many soldiers lost their limbs and some died from it. But today, we know a lot about how to prevent and treat it.

👩🏽⚕️ Additional questions (FAQs)
💬 What kind of disease is Trench Foot?
This became very popular during World War I because soldiers' legs rotted ('trench' means trench). But even today, if you keep your feet in the cold (water or mud) for a week or so with wet socks/shoes, the cold causes the blood vessels in your legs to contract, stopping blood flow and causing the flesh to rot.
💬 How do you make your legs look good when this happens?
First, the leg becomes ice cold, numb, white, and shriveled (just like fingers become when they are in water for a long time). Then, when the leg is warmed up, there is an unbearable burning pain (pins and needles), the leg turns red, large blisters and sores appear, and finally the leg turns black (gangrene) and begins to rot.
💬 Is it okay to heat up your feet immediately when they get cold?
No! Never heat the leg with fire or hot water all at once (this will further damage the tissue). In this case, all mud and moisture should be removed, the skin should be dried thoroughly, covered with a soft cloth and allowed to warm slowly to room temperature. If it is rotten, the severe parts should definitely be cut out and removed surgically.
