hi xMama2Fourx ,from the pictures u have sent and history u have given it seems like hand eczema to me also called hand dermatitis ,which is caused due to allergy to many substances,especially in housewives detergents and soaps are major culprits or other new chemicals they come in contact with.this is especially very itchy ,i would also like to know if the bumps seems to fill with fluid or is very firm in nature.if blisters seems fluid filled and tend to break easily while scratching its more likely to be eczema of hand .For which i advise u to keep your hand dry as far as possible but if u have to use soaps and detergents try to use vinyl gloves and avoid rubber gloves but take care not use gloves for longer period of time coz sweats may also aggravate the condition . You can use mild emollients if its very dry and some topical steroids to reduce the inflammation.To find the possible allergen u can go though the patch test.
