What causes Eczema blisters: diagnosis, symptoms and treatment

Eczema blisters appear on the palms, sides of fingers and on the feet. They are mostly caused by dyshidrotic eczema, also known as dyshidrosis. Women are more prone than men. Eczema blisters are common during middle ages.

There is no cure for eczema blisters. In fact, their actual cause remains unknown. A number of dyshidrotic eczema treatment options are however available to encourage recovery, prevent from infection and ease itchiness. Given enough time, the blisters do heal on their own, mostly after a period of 3 weeks.

What causes eczema blisters on fingers, palms and feet?

As to what causes eczema blisters, three eczema types are responsible:

  • Dyshidrotic eczema – this is the most common cause of eczema blisters. It occurs on fingers, palms and the feet.
  • Irritant contact eczema – this eczema type is caused by contact with irritants such as acids, alkalines, detergents, poison ivy and metals.
  • Allergic contact eczema type occurs after contact with allergens such as some foods and medications, dust mites, pets and cosmetics.

People with sensitive skins are more prone to eczema blisters. The blisters are noted to worsen in times of physical or emotional stress.

People with a history of atopic eczema are also more likely to develop eczema blisters due to dyshidrosis. Other possible causes include humid weather, immune suppressing diseases and sweaty feet or hands.

Symptoms

  • Burning sensation and itch on palms, fingers or feet
  • Tiny and itchy blisters
  • The blisters form clusters and worsen when scratched
  • Excessive sweating on palms and feet
  • Thickening and changes in color of the nails
  • Drying and flaking on affected skin regions

Itchiness on palms and feet usually begins before the blisters appear. It gets worse in the second week, especially without proper treatment.

How to treat eczema blisters

Eczema blisters do not require specialized treatment. They will heal in about 3 weeks. However, flare-ups may keep coming back even before the initial blisters heal over and go away. Below are the available treatment options:

Moisturizers

If the blisters are large enough, your doctor may decide to drain them. Water blister should not be drained at home, for it can make the situation worse and invite infections.

Immune modulators 

Frequent flares are sometimes treated with immune modulators. These are medications that inhibit the immune system to prevent from overreaction. Treatment with these medications predisposes patients to other infections. It should be done under the guidance of a doctor.

Phototherapy

UVB rays can be used to encourage the skin to recover naturally. In most cases, phototherapy is used in conjunction with other eczema blisters treatments.

Medications to control excess sweating on hands and feet may also be administered, especially for frequently recurrent flares.
