Hi!! According to your history it seems to be a case of hand eczema which can be endogenous due to internal sensitivity of the individual or due to external factors. You should try to find out whether you are allergic to any chemical or vegetable material and if yes avoid it. You should avoid frequent washing of hands, avoid harsh soaps and detergents, keep your hands moisturized, avoid washing clothes and utensils and if required wear gloves. You can apply cosvate G prescribed to you but also use agood quality moisturizing cream like venussia max on your hands frequently and liberally. Also take tablet levocetrizine at night for few days till itching subsides. Hope for your speedy recovery.
