My husband has white blisters on his palms that come and go. He says they are not painful nor itchy and we are aware it is the result of his job description- his hands work vigoriously with chemicals and are constantly wet... As they tend to dissapear after the ''required time'' before having to see a doctor, i was wondering if in time with this basically being an allergic reaction everytime, is this going to cause some deep dermicalogical unrepairable damage when he is older....?
