For Those Concerned About Cellulitis Associated With Lymphedema

We are Mukumi Clinic, a lymphedema specialty clinic located in Yoyogi, Tokyo.

If you have lymphedema, it is important to be aware not only of swelling in the arms or legs, but also of a skin infection called cellulitis. When cellulitis develops, it can cause symptoms such as redness, warmth, swelling, and pain. In some cases, it may also be accompanied by fever and general fatigue.

This page explains why people with lymphedema are more prone to cellulitis, the main symptoms to watch for, when to seek medical attention, how to prevent cellulitis, and key points for preventing recurrence.

What Is Cellulitis, a Common Complication of Lymphedema?

Cellulitis is a bacterial infection of the skin and subcutaneous tissue

Cellulitis is an infection that occurs when bacteria enter the skin or subcutaneous tissue. It can be triggered by minor cuts, insect bites, cracked skin, athlete’s foot, or small wounds around the nails.

The main symptoms are redness, warmth, swelling, and pain in the affected area. As the condition progresses, systemic symptoms such as fever, chills, and fatigue may also appear.

Extra caution is needed in areas affected by lymphedema

In areas affected by lymphedema, lymphatic flow tends to be impaired, and the skin’s barrier function may also become weaker. As a result, even a small wound that would not usually lead to infection may become an entry point for bacteria.

When cellulitis occurs, inflammation can temporarily worsen swelling. If cellulitis recurs, it is also important to review daily skin care, compression therapy, and the way compression garments are used.

Why Does Cellulitis Occur More Easily in People With Lymphedema?

The skin tends to become dry, and its barrier function may decline

The skin has a barrier function that helps prevent bacteria and other external substances from entering the body. However, in areas affected by lymphedema, the skin may become dry or hardened.

When the skin is dry or cracked, bacteria can enter more easily. Even minor skin problems can trigger cellulitis, which is why skin care, including moisturizing, is important.

Impaired lymphatic flow may reduce local defense against infection

The lymphatic system not only transports excess fluid and waste products from the body, but also plays an important role in protecting the body from infection. In lymphedema, lymphatic flow is impaired, and the local defense against bacteria in the affected area may be reduced.

As a result, when bacteria enter an arm or leg affected by lymphedema, inflammation may spread more easily, increasing the risk of cellulitis.

Minor cuts, insect bites, and athlete’s foot can become triggers

Cellulitis can occur even when there is no obvious injury.

For example, scratches from insect bites, cracks caused by dry skin, wounds around the nails, and shoe blisters can all become triggers. In people with lower-limb lymphedema, athlete’s foot can also serve as an entry point for infection.

Fatigue, stress, and poor physical condition may also act as triggers

Cellulitis may be more likely to occur when you are fatigued, sleep-deprived, stressed, or feeling unwell. When the body’s defenses are temporarily weakened, even a small skin problem can lead to infection.

Symptoms of Cellulitis in People With Lymphedema

Redness, warmth, swelling, and pain

Cellulitis may cause redness and warmth in the infected area. Typical symptoms include an area affected by lymphedema appearing redder than usual, feeling hot to the touch, becoming more swollen, or becoming painful when pressed.

If the redness is gradually spreading or the pain is strong, the inflammation may be progressing.

Fever, chills, and fatigue

Cellulitis may cause not only skin symptoms, but also systemic symptoms such as fever, chills, and fatigue. A sudden high fever, severe tiredness that makes it difficult to move, or chills may indicate that inflammation from the infection is affecting the whole body.

Red spots and blisters

When inflammation is severe, red spots may appear on the skin, and blisters may develop. The skin may also feel tight, stinging, or more painful than usual.

Cellulitis can worsen lymphedema

Inflammation caused by cellulitis can temporarily increase swelling. Repeated episodes of cellulitis may also worsen lymphedema over time.

For this reason, preventing recurrence remains important even after cellulitis has been treated.

What to Do When Cellulitis Is Suspected｜What You Can Do at Home and What to Avoid

Rest and avoid overusing the affected area

If cellulitis is suspected, the first step is to rest the affected arm or leg and avoid unnecessary movement. Exercise, prolonged walking, and carrying heavy objects should preferably be avoided while symptoms are present.

If the affected area feels very hot, cooling it may help relieve discomfort. However, avoid cooling methods that may damage the skin, such as applying ice directly for a long period of time.

Do not massage or apply strong compression on your own judgment

If cellulitis is suspected, avoid lymphatic massage or strong compression based on your own judgment. Strong stimulation of an inflamed area may increase pain or worsen symptoms.

If you normally use compression stockings or compression sleeves, it is important to ask your doctor whether you should continue using them when redness, pain, or fever is present.

Avoid bathing, exercise, and alcohol while symptoms are present

When fever, marked redness, or pain is present, bathing, exercise, and alcohol consumption may increase blood flow and worsen redness or pain. While symptoms are present, avoid long baths, strenuous exercise, and drinking alcohol.

Keeping the body clean is important, but it is also important not to rub the affected area strongly and to minimize irritation. If symptoms are severe, consult a doctor about whether bathing or showering is appropriate.

Consult a medical institution

Cellulitis is an infection that often requires treatment with antibiotics. If you have redness, warmth, pain, or swelling, or if these symptoms are accompanied by fever, chills, or fatigue, seek medical attention promptly.

In particular, if redness spreads rapidly, high fever is present, pain is severe, or blisters appear, it is important to consult a medical institution as soon as possible.

Diagnosis and Treatment at a Medical Institution

The doctor will assess the degree of redness, swelling, pain, and fever

During the examination, the doctor will check the extent of redness, warmth, swelling, and pain. The presence of systemic symptoms such as fever, chills, and fatigue is also important for evaluation.

The doctor will also check for possible entry points for bacteria, such as wounds, insect bites, athlete’s foot, or inflammation around the nails.

Blood tests may be performed to assess inflammation if needed

If symptoms are severe or systemic symptoms are present, blood tests may be performed. Inflammatory markers such as the white blood cell count and C-reactive protein, or CRP, may be checked to evaluate the severity of infection.

In some cases, it is also necessary to distinguish cellulitis from other conditions. Redness and swelling do not always mean cellulitis, so evaluation by a doctor is important.

Treatment mainly involves oral or intravenous antibiotics

Treatment for cellulitis involves antibiotics that target the bacteria causing the infection. If symptoms are relatively mild, oral antibiotics may be used. If fever is high or redness and swelling are spreading, intravenous antibiotics may be required.

Hospitalization may be necessary when symptoms are severe

Hospitalization may be needed if there is a high fever, rapidly spreading redness or swelling, severe pain, or difficulty taking enough food or fluids. In such cases, intravenous treatment and general medical management may be necessary.

People with diabetes, reduced immunity, or those undergoing cancer treatment may be at higher risk of developing severe infection.

Prevention of Cellulitis in People With Lymphedema

Keep the skin clean and continue moisturizing

Keeping the skin clean is a basic step in preventing cellulitis. Do not leave sweat or dirt on the skin. Wash gently during bathing or showering and keep the skin clean.

Cracks caused by dry skin can become entry points for bacteria. After washing, use a moisturizer to prevent dryness. It is especially important to regularly check areas affected by lymphedema for redness, wounds, itching, or cracks.

Prevent wounds, insect bites, and athlete’s foot

Minor wounds, insect bites, and athlete’s foot can all trigger cellulitis.

In daily life, try to avoid skin irritation and injuries as much as possible. Be careful not to injure the skin when trimming nails, avoid scratching insect bites, and prevent shoe blisters.

In people with lower-limb lymphedema, athlete’s foot between the toes can serve as an entry point for infection. If you notice peeling or itching of the feet, seek treatment early from a dermatologist or other medical professional.

Continue using compression garments and compression therapy appropriately

Lymphedema management often includes compression garments such as compression stockings or sleeves, as well as compression therapy.

Proper control of swelling is thought to help maintain skin condition and may also help prevent recurrence of cellulitis.

LVA Surgery Can Be Effective for Cellulitis

If cellulitis recurs repeatedly, surgical treatment for lymphedema itself may be considered in addition to conservative treatment.

Lymphaticovenular anastomosis, or LVA, is a surgical procedure that connects lymphatic vessels to veins with the aim of improving lymphatic fluid flow.

In a 2024 randomized controlled trial conducted by Dr. Mihara, Dr. Hara, and colleagues at our clinic, patients who received conservative treatment alone were compared with patients who received conservative treatment combined with LVA. The study reported that the frequency of cellulitis was significantly reduced in the group that underwent LVA in addition to conservative treatment.

LVA can be considered an effective treatment option for patients with lymphedema who experience recurrent cellulitis.

Frequently Asked Questions About Lymphedema and Cellulitis

Q1. Why are people with lymphedema more likely to develop cellulitis?

In arms or legs affected by lymphedema, lymphatic flow tends to be impaired, and the skin may become dry or hardened. As a result, the skin’s barrier function may decline, making it easier for bacteria to enter through small wounds, insect bites, cracks, athlete’s foot, or injuries around the nails.

Cellulitis is an infection that occurs when bacteria enter the skin or subcutaneous tissue. In areas affected by lymphedema, even a minor skin problem that would not normally cause a major issue may trigger cellulitis.

If redness, warmth, swelling, or pain appears in an arm or leg affected by lymphedema, it is important to consult a medical institution promptly.

Q2. If an arm or leg affected by lymphedema becomes red, does that mean it is cellulitis?

If redness appears in an arm or leg affected by lymphedema, cellulitis is one possible cause. However, redness is not caused only by cellulitis. Other conditions, such as dermatitis, insect bites, eczema, inflammation of the veins, injury, or blood clots may also be involved.

Cellulitis should be suspected especially when redness is accompanied by warmth, pain, worsening swelling, fever, chills, or fatigue.

If the redness spreads rapidly or you have unusually strong pain, do not simply wait and see based on your own judgment. Please seek medical attention early.

Q3. What symptoms occur with cellulitis?

Common symptoms of cellulitis include redness, warmth, swelling, and pain in the affected area. In areas affected by lymphedema, you may also feel that the swelling has become stronger than usual.

When symptoms are severe, systemic symptoms such as fever, chills, fatigue, and joint-like pain may occur. If the inflammation is strong, red spots or blisters may also appear on the skin.

If you feel that “this swelling is different from usual,” “the area suddenly became red,” “it feels hot to the touch,” or “there is pain,” cellulitis should be considered.

Q4. If I do not have a fever, does that mean it is not cellulitis?

Cellulitis is still possible even if you do not have a fever.

Cellulitis can be accompanied by fever, but in the early stage, it may begin only with redness, warmth, swelling, and pain. In areas affected by lymphedema, symptoms may sometimes start in a subtle way.

Do not assume that everything is fine just because there is no fever. If redness is spreading, pain is strong, swelling is worse than usual, or the area feels hot to the touch, consult a medical institution early.

Q5. What should I do at home if cellulitis is suspected?

If cellulitis is suspected, first rest the affected arm or leg. Avoid excessive walking, standing for long periods, or carrying heavy objects.

If warmth or pain is strong, gentle cooling may help you feel more comfortable, as long as it does not burden the skin. However, avoid cooling methods that may damage the skin, such as applying ice directly for a long time.

If you have fever, chills, severe fatigue, rapidly spreading redness, severe pain, or blisters, you need to seek medical attention promptly. Even at night or on holidays, if symptoms are severe, consider visiting an emergency department or a nearby general hospital.

Q6. Are there things I should not do when I have cellulitis?

If cellulitis is suspected, avoid lymphatic massage or strong compression based on your own judgment. Strongly stimulating an inflamed area may increase pain or worsen symptoms.

When fever, marked redness, or pain is present, it is also better to avoid long baths, saunas, strenuous exercise, and alcohol. Increased blood flow may worsen redness or pain.

It is not advisable to forcefully massage the area because you think the swelling should be “drained.” The priority should be treatment of the infection.

Q7. Can I use compression stockings or compression sleeves when I have cellulitis?

During the acute stage when cellulitis is suspected, compression with compression stockings or compression sleeves may need to be temporarily avoided.

If redness, warmth, pain, or fever is present, continuing compression forcefully may worsen pain or increase the burden on the skin.

However, whether compression therapy should be continued or temporarily stopped depends on the severity of symptoms and the condition of the lymphedema. Do not decide on your own whether to continue or stop compression. Please check with your doctor or a lymphedema specialist.

Q8. Can I receive lymphatic massage or lymphatic drainage when I have cellulitis?

When symptoms of cellulitis are present, lymphatic massage and lymphatic drainage are generally temporarily avoided.

Stimulating an inflamed area may increase pain or worsen inflammation. If cellulitis is suspected, rest and antibiotic treatment should be prioritized.

These treatments can usually be resumed after redness, warmth, pain, fever, and other symptoms have improved. Even if symptoms appear to have settled, do not decide on your own when to restart. Discuss the timing with your doctor or a lymphedema specialist.

Q9. Which medical department should I visit for cellulitis associated with lymphedema?

If an arm or leg affected by lymphedema develops redness, warmth, pain, or swelling, you can consult a dermatology department, plastic surgery department, or lymphedema clinic.

If you developed lymphedema after cancer treatment, it may also be an option to consult the doctor who treated your cancer, or your specialist in breast surgery, gynecology, urology, or another relevant department.

If you have a high fever, rapidly spreading redness, severe pain, difficulty walking, difficulty taking enough food or fluids, diabetes, or reduced immunity, intravenous treatment or hospitalization may be required. In such cases, consult a general hospital or emergency department promptly.

Q10. What kind of treatment is performed for cellulitis?

Treatment for cellulitis involves antibiotics that target the bacteria causing the infection. If symptoms are relatively mild, oral antibiotics may be used.

If fever is high, redness or swelling is spreading, pain is severe, or the general condition is poor, intravenous antibiotics or hospitalization may be necessary.

During the examination, the doctor will check the extent of redness, warmth, swelling, pain, and whether fever is present. If needed, blood tests may also be performed to check inflammatory markers such as the white blood cell count and CRP.

Q11. Can antibiotics prevent cellulitis from recurring?

Antibiotics are used to treat infection when cellulitis develops. However, taking antibiotics does not necessarily prevent recurrence.

To prevent recurrent cellulitis, it is important to keep the skin clean, continue moisturizing, prevent wounds and insect bites, treat athlete’s foot, and manage lymphedema appropriately.

Do not start antibiotics or stop them midway based on your own judgment. The type and duration of antibiotics should be determined by a doctor according to your symptoms and overall condition.

Q12. If cellulitis recurs repeatedly, can lymphedema worsen?

When cellulitis occurs, inflammation can temporarily worsen swelling. Repeated episodes of cellulitis may also worsen lymphedema over time.

Therefore, cellulitis should not be treated only when it occurs. Preventing recurrence is very important.

If cellulitis recurs, it is necessary to check whether compression garments fit properly, whether compression methods are appropriate, whether there is skin dryness or athlete’s foot, and whether daily activities are creating situations in which wounds easily occur.

Q13. What can I do in daily life to prevent cellulitis?

The basics of cellulitis prevention are keeping the skin clean and continuing moisturization. Wash gently during bathing or showering, and after washing, use a moisturizer to prevent dry skin.

It is also important not to scratch insect bites, not to injure the skin when trimming nails, to prevent shoe blisters, to avoid cutting nails too short, and to avoid injuries from pet claws or plant thorns.

In people with lower-limb lymphedema, athlete’s foot between the toes can become an entry point for cellulitis. If you notice peeling, itching, or moist skin changes on the feet, consult a dermatologist or other medical professional early.

Q14. If cellulitis recurs, should I consult a lymphedema specialist clinic?

If cellulitis recurs repeatedly, we recommend consulting a lymphedema specialist clinic.

Recurrent cellulitis may involve multiple factors, including dry skin, wounds, athlete’s foot, poorly fitting compression garments, insufficient compression therapy, and progression of lymphedema.

At a specialist clinic, the condition of the lymphedema can be assessed comprehensively. Skin care, compression therapy, compression garments, lifestyle precautions, and surgical treatment when necessary can all be considered together.

Q15. If cellulitis recurs repeatedly, can LVA surgery be an option?

For lymphedema with recurrent cellulitis, lymphaticovenular anastomosis, commonly known as LVA surgery, may be an option in addition to conservative treatment.

LVA is a microsurgical procedure that connects lymphatic vessels to veins under a microscope, with the aim of improving lymphatic fluid flow. Improving lymphatic flow may help control swelling and prevent recurrence of cellulitis.

However, the effect is not the same for everyone. Surgical indication is determined based on the condition of the lymphedema, the remaining lymphatic vessels, the frequency of cellulitis, the condition of the skin, and the course of previous treatments.

At our clinic, we combine conservative therapy, lymphatic ultrasound, and LVA surgery to consider a treatment plan tailored to each patient’s condition.

Q16. If I undergo LVA surgery, will cellulitis disappear completely?

LVA surgery can be expected to reduce the frequency of cellulitis, but it is not a treatment that can guarantee cellulitis will disappear completely.

Recurrence of cellulitis is influenced not only by lymphatic flow, but also by many other factors, including dry skin, wounds, athlete’s foot, poor physical condition, fatigue, and diabetes.

Therefore, even after LVA surgery, it is important to continue lymphedema management, including moisturizing, skin care, wound prevention, compression garments, and compression therapy. By combining surgery with daily care, we aim to achieve a more stable condition.

Q17. In what situations should I seek medical attention early?

Please consult a medical institution promptly if you have any of the following symptoms:

・Redness, warmth, swelling, or pain in an arm or leg affected by lymphedema

・Spreading redness

・Fever, chills, or severe fatigue

・Strong pain

・Blisters

・Difficulty with daily activities, such as difficulty walking or moving the arm

In particular, caution is needed if you have a high fever, rapidly spreading redness, confusion or reduced alertness, inability to take fluids, diabetes, reduced immunity, or are undergoing cancer treatment. Even at night or on holidays, consider visiting an emergency department or general hospital.

Q18. After cellulitis has improved, when can I restart lymphedema care?

After cellulitis has improved, lymphedema care can be restarted once symptoms such as redness, warmth, pain, and fever have settled.

The timing for restarting compression stockings or sleeves, lymphatic drainage, and exercise therapy varies depending on the severity of symptoms and the condition of the skin.

Even if symptoms appear to have settled, suddenly restarting strong compression or massage may lead to pain or skin problems. We recommend deciding when and how to restart care in consultation with your doctor or a lymphedema specialist.

Summary｜If You Have Redness, Warmth, or Fever With Lymphedema, Seek Medical Advice Early

People with lymphedema may develop cellulitis as a complication. If redness, warmth, swelling, or pain appears in an arm or leg, or if these symptoms are accompanied by fever, chills, or fatigue, it is important not to ignore them based on your own judgment. Please consult a medical institution promptly.

To prevent cellulitis, it is important to keep the skin clean, continue moisturizing, prevent wounds, insect bites, and athlete’s foot, and manage lymphedema appropriately. During the acute stage, avoid massage and strong compression. Once inflammation has settled, restart lymphedema care based on your doctor’s guidance.

If cellulitis recurs repeatedly, reviewing daily care and conservative treatment is important, and LVA surgery may also be an option. If you have concerning symptoms or repeated episodes of cellulitis, we recommend consulting a specialist early.
