This may be case of contact dermatitis or dishydrosis. Dishydrosis may start as vesicles or bumps containing clear fluid. These bumps are usually covered by a thick clear membrane. Itchiness may ensue which initiates an itch scratch cycle. This itch scratch cycle will lead to an eczematous skin reaction presenting with excoriations.
Avoid prolonged exposure to water. Topical corticosteroids may be applied thinly over the area to help ease the swelling and redness. Use only mildly potent ones. An antifungal medication may also be used if the skin condition does not readily respond to the steroids. Close supervision by a physician is needed when using steroids due to side effects.
