Welcome to healthcare Magic
You seem to have Pompholyx(Dishydrotic eczema). It is a type of eczema. Cause for this can be contact allergens like nickel, cobalt, ingested metals, nuts, infections elsewhere like tinea
, or bacterial. People who sweat more from palms an soles get this more often. Most of the patients are atopics. It might be seasonal, so environment has a great role to play.
When it is itchy you can apply a mid potent steroid
twice a day.
You can find more details if you search for dyshidrotic eczema
