Occasionally have small deep blisters that form on my hands and feet.
So I did some research and found out the following.
Pompholyx usually starts as intense itching and burning of the skin on the hands and fingers. The palms and sides of the fingers (and sometimes the soles of the feet) then erupt into tiny itchy blisters that may weep (leak) fluid.
In severe cases, the blisters may be quite large and may spread to the backs of the hands, feet and limbs.
The skin can sometimes become infected. Signs of an infection can include the blisters becoming very painful and oozing pus or becoming covered in a golden crust.
The blisters will usually heal within a few weeks. The skin tends to become dry and crack or peel as it starts to heal.
It's not clear exactly what causes pompholyx, but it may be triggered or made worse by:
a fungal skin infection – this may be on the hands or at a distant site from the blisters (such as in between the toes) and will need treating
a reaction to something that has touched your skin – such as certain metals (particularly nickel), detergents, household chemicals, soap, shampoo, cosmetic products or perfume
stress
sweating – pompholyx is more common in spring and summer, in warmer climates, and in people with hyperhidrosis(external link opens in a new window / tab) (excessive sweating)
