I really do not know what happened in my wife's fingers and hands, suddenly last saturday she got little blisters at her left hand fingers an hands, the right hand developed the same but in minor qtys, and a liitle ones at her finger foot.she went to a non dermatology doctor and he said that can be an allergy problem. There was no other sympotms, in our city we reached almost 38 celciuos last weekend and she is under very deep strees because personal family problems with her mother. Blisters are at fingers side and had water inside, some of them already gone but left some crusts and are swollen, she never got itch or pain. Can this be an allergy problem or other more serious problem? please let us know
