What are the symptoms of dyshidrotic eczema. How can you effectively treat summer finger bumps. What triggers dyshidrotic eczema flare-ups. How does diet impact this skin condition. What are the best at-home remedies for managing dyshidrotic eczema.
What is Dyshidrotic Eczema: Unveiling the Mystery of Summer Finger Bumps
Dyshidrotic eczema, also known as pompholyx, is a distinctive type of eczema characterized by the formation of small, itchy blisters on the hands and feet. These blisters, often referred to as “summer finger bumps,” can cause significant discomfort and affect a person’s quality of life. Understanding this condition is crucial for effective management and treatment.
Dyshidrotic eczema is not a permanent condition, but rather one that involves periodic flare-ups. These episodes typically last several weeks and can recur anywhere from monthly to annually. While some individuals may experience only one flare-up, many face repeated episodes throughout their lives.
The Origin of the Term “Pompholyx”
The alternative name “pompholyx eczema” has an interesting etymology. “Pompholyx” is derived from the Ancient Greek word for “bubble,” aptly describing the appearance of the blisters associated with this condition.
Recognizing the Symptoms: Identifying Dyshidrotic Eczema
Dyshidrotic eczema presents with a range of distinctive symptoms that set it apart from other skin conditions. Recognizing these symptoms is key to early diagnosis and prompt treatment.
- Intense itching
- Burning or prickling sensations
- Sudden appearance of small, deep-seated blisters
- Painful drying and cracking of the skin
- Swelling and changes around the nails
The blisters associated with dyshidrotic eczema have a unique appearance, often likened to tapioca pudding. They typically start small and may grow larger over time. These water-filled blisters can appear on the sides of fingers, palms, toes, and soles of the feet.
Do the blisters appear in other areas of the body? No, dyshidrotic eczema blisters are localized to the hands and feet. If similar blisters appear elsewhere, it may indicate a different form of eczema or another skin condition entirely.
Unraveling the Causes: What Triggers Dyshidrotic Eczema?
While the exact cause of dyshidrotic eczema remains elusive, researchers have identified several potential triggers that may contribute to flare-ups:
- Stress
- Metal allergies or sensitivities (particularly nickel)
- Seasonal allergies

What to know about summer finger bumps
Dyshidrotic eczema is a type of eczema that produces skin blisters on the feet and hands. These small blisters are sometimes known as “summer finger bumps.”
Doctors may also refer to dyshidrotic eczema as dyshidrosis, pompholyx, foot-and-hand eczema, vesicular eczema, or palmoplantar eczema.
The blisters or bumps that form can be uncomfortable, itchy, and painful. People may feel a burning or prickly sensation in their skin. The blisters are not permanent.
Dyshidrotic eczema involves flare-ups that last several weeks. Although some people may only experience one flare, people usually have repeated flare-ups that may occur from once every month to once every year.
Below, we look at the symptoms, causes, risk factors, and treatment options for dyshidrotic eczema, as well as how diet may impact this condition.
Doctors sometimes call dyshidrotic eczema “pompholyx eczema.”
Pompholyx is the word for “bubble” in Ancient Greek. The condition can produce intensely itchy blisters on the skin that can also be painful or have a burning sensation. These blisters are tiny and deep-seated and may have a similar appearance to tapioca pudding.
Water-filled blisters can appear on the sides of the fingers and may extend to the palms of the hands. They can also appear on the toes and soles of the feet.
People with this type of eczema may also have other types of eczema elsewhere on the body.
Dyshidrotic eczema may occur as a one-time episode. However, it often occurs as a chronic condition that involves repeated flare-ups.
Symptoms of dyshidrotic eczema include:
- extreme itching
- burning sensation
- a sensation of heat in the palms or soles
- prickling sensation
- the sudden appearance of small blisters, often on the sides of the fingers
- painful drying and cracking of the skin
- swelling and changes to the skin around the nail
The blisters start small and then may grow bigger. They may weep fluid and produce discoloration. They do not appear in other places on the body.
If a person has small, water-filled blisters elsewhere, it may be another form of eczema or another skin condition.
The bumpy blisters on the sides of the fingers may develop as a result of excessive sweating or heat exposure. This is why people sometimes refer to them as “summer finger bumps.”
There is no definitive known cause for dyshidrotic eczema. However, some factors that may trigger flare-ups include:
- stress
- metal allergies or sensitivities, such as a nickel allergy
- other types of allergies, such as seasonal allergies
- sweating
- hot, humid weather
According to the National Eczema Society, half of those with dyshidrotic eczema also have atopic eczema or a family history of the skin condition.
Dyshidrotic eczema is more common in people under 40 years of age. It is also more common in females.
According to the American Academy of Dermatology, other risk factors include:
- having another type of eczema
- having seasonal allergies or asthma
- having an allergy to certain metals
- having feet or hands that frequently sweat or become wet
- having a family history of dyshidrotic eczema
- working with metals
- being a mechanic
- working with cement
A person with symptoms of dyshidrotic eczema should see a doctor or dermatologist for a diagnosis.
The doctor will examine the person’s skin and take a medical and family history to determine a diagnosis and treatment plan.
A doctor may also recommend allergy testing to check for specific triggers that may be exacerbating the eczema.
There is no cure for dyshidrotic eczema. However, there are ways to manage the condition. A doctor may prescribe:
- medical moisturizer
- wet soaking with potassium permanganate to help with oozing blisters
- topical steroids to reduce inflammation
- a topical calcineurin inhibitor such as tacrolimus ointment (Protopic)
- oral antibiotics to combat bacterial infection
- oral immunosuppressant drugs
- Botox injections
- phototherapy
Dealing with a flare-up of dyshidrotic eczema can be difficult. The condition is often very itchy and can be painful and bothersome.
The National Eczema Society suggests some strategies for at-home relief, including:
- washing with lukewarm water because very hot or cold water may irritate the skin
- using an emollient soap or cleanser instead of regular soap
- avoiding direct contact with skin-irritating ingredients or products such as detergents and cleansing agents
- taking antihistamines with a sedative effect that will help with sleep rather than actively treat itchiness
- draining large, painful blisters with a sterile needle
- bandaging or wrapping the skin after applying creams or ointments
Stress management can also help prevent flare-ups.
Dietary triggers may contribute to flare-ups for some people. Avoiding these foods can help prevent symptoms.
As a nickel allergy may have a link to dyshidrotic eczema, it is possible that avoiding foods high in nickel may help prevent flare-ups. These foods include:
- soy products, such as soy sauce and tofu
- licorice
- cocoa powder
- clams
- cashews
- figs
An infection may develop as the blisters grow larger and the condition compromises the skin barrier.
Some people may also have fungal infections at the same time as they experience dyshidrotic eczema flare-ups.
If a person with dyshidrotic eczema develops a skin infection, they should see a doctor for evaluation so they can receive treatment.
Some symptoms of a skin infection include:
- discoloration
- swelling
- oozing pus
- pain
- warmth
Preventing flares involves avoiding known triggers such as allergens or temperature changes. Other strategies for preventing dyshidrotic eczema and its symptoms include:
- applying moisturizer to prevent dryness and cracking
- wearing gloves, socks, or tights made with cotton, silk, or bamboo to allow the skin to breathe
- removing rings before washing the hands, applying moisturizer, or sleeping to avoid skin irritation
It can be challenging to live with dyshidrotic eczema because it affects the hands and feet.
Some people with the condition may not be able to work during flare-ups. They may also have trouble walking if they develop painful blisters on their feet.
However, it is possible to manage this type of eczema. People with dyshidrotic eczema should talk with a doctor to find an appropriate treatment option.
Dyshidrotic eczema can cause small fluid-filled bumps or blisters to appear on the feet or hands.
Various factors can trigger a flare-up of dyshidrotic eczema. These may include dietary and environmental allergens, stress, weather conditions, and sweat.
A doctor can help people with dyshidrotic eczema find an appropriate treatment option.
A combination of treatment and prevention strategies can help a person manage the symptoms of dyshidrotic eczema.

Heat rash (prickly heat) – NHS
Heat rash is uncomfortable, but usually harmless. It usually gets better on its own after a few days.
Check if you have heat rash
The symptoms of heat rash are:
- small, raised spots
- an itchy, prickly feeling
- mild swelling
The rash often looks red, but this may be less obvious on brown or black skin.
The symptoms of heat rash are often the same in adults and children.
It can appear anywhere on the body and spread, but it cannot be passed on to other people.
Heat rash appears as raised spots that are 2mm to 4mm across. Some spots may be filled with fluid.

If you’re not sure if your child has heat rash
Look at other rashes in children.
How you can treat or prevent heat rash yourself
The main thing to do is keep your skin cool so you do not sweat and irritate the rash.
To keep your skin cool
- wear loose cotton clothing
- use lightweight bedding
- take cool baths or showers
- drink plenty of fluid to avoid dehydration
To calm the itching or prickly feeling
- apply something cold, such as a damp cloth or ice pack (wrapped in a tea towel) for up to 20 minutes
- tap or pat the rash instead of scratching it
- do not use perfumed shower gels or creams
A pharmacist can help with heat rash
Speak to a pharmacist about heat rash. They can give advice and suggest the best treatment to use.
A pharmacist might recommend:
- calamine lotion
- antihistamine tablets
- hydrocortisone cream – though not for children under 10 or pregnant women as they need to get advice from a doctor before using this treatment
Non-urgent advice: See a GP if:
- the rash does not improve after a few days
- your baby has a rash and you’re worried
Causes of heat rash
Heat rash is usually caused by excessive sweating.
Sweat glands get blocked and the trapped sweat leads to a rash developing a few days later.
Babies often get heat rash because they cannot control their temperature as well as adults and children can.
