What Causes Eczema Blisters on the Hands and Feet?

Many of the greatest scientific minds share the common theory and conclusion that an allergic reaction to the metal known as nickel causes dyshidrotic eczema. Human sweat even contains high levels of nickel. The term dyshidrotic translates ‘disordered sweat’. The name arose during the 1800s because so-called medical doctors believed sweat caused the outbreak.

Nowadays, the disorder is known by a variety of monikers such as pompholyx, palmoplantar eczema, foot-and-hand eczema, and vesicular eczema. Interestingly, ‘pompholyx’ is a Greek word that translates into ‘bubble’ which denotes the appearance of the large fluid-filled blisters. The condition is excruciating and often crippling. In extreme causes, walking becomes impossible.

Women between the ages of 20 to 40 seem to be at the most significant risk. Many medical professionals also think cobalt, balsam and bacterial infections or fungal infections might also coax the condition to arise. Some say hay fever and seasonal allergies spur the condition to arise.

Home Remedies for Dyshidrotic Eczema

Many who suffer from dyshidrotic eczema list their pain threshold as a ten. It is by far the worst of all eczema types. However, there are ways to treat the blisters at home and find some relief.

Cold compresses applied for 15 minutes

  • Lotion
  • Moisturizing creams
  • Frequent washing
  • Limited showers (10 minutes or less)
  • Avoid hot water and hot tubs
  • Apply a moisturizer right after bathing or showering

Blisters on the Feet

The worse aspect of this condition is the chronic blisters on the feet. Many people can barely walk. To avoid sweating, which seems to make the lesions worse, wear sandals. If you must don a pair of shoes, then pick lightweight nylons or cotton socks to protect your feet from rubbing against the interior of the shoe. Try not to scratch the blisters on the soles of your feet which can make it worse. It is not uncommon to be unable to walk or work during a severe outbreak. You might also end up suffering insomnia because of the constant pain and itching. Lack of sleep puts you at risk of developing infections or catching a virus.

Long-Term Outlook

The blisters can last up to four weeks. Even after the blisters clear, your skin will still be red, crusty, scaly and sensitive. You should avoid scratching, or you could cause scarring and permanent pigmentation discoloration. Once the blisters pop, bacteria can invade the open wounds and cause severe secondary infections which can delay recovery. Sadly, the condition can reoccur. It often happens twice a year. If nickel is the underlying cause of your eczema, then you should alter your lifestyle to gain much-needed long-term relief.
