Dyshidrotic eczema is a form of hand eczema with itching and burning micro blisters on the hands and sometimes feet. It is common and young adults it may be associated with hand and foot sweating or a history of eczema.
Multiple factors may contribute to flares including underlying genetic tendency and contact with irritants such as soaps, water, and friction. It may also rarely be seen as a result of a contact allergy such as to nickel or as an ID reaction (a response to a fungal infection at another location).
Treatment involves addressing any underlying aggravating factors such as the irritating effects of water or detergents. General home measures for mild cases include using cold pack, soothing emollient creams, wearing gloves during wetwork, and even attempting antiperspirant on palms to improve sweating.
