You may be suffering from hand eczema which is a kind of irritant contact dermatitis due to use of detergents during washing of clothes or utensils. Cracks and thickened skin on palms can also be due to psoriasis. Please avoid detergent for some time. You can call me or do online consult with photos for detailed prescriptions and other instructions to reduce the recurrence.

Sounds like hand eczema. it responds very well to treatment. wearing rubber gloves while washing clothes /utensils and applying a moisturizer immediately after hand washing will help. see a Dermatologist in person or on private chat to get a detailed insight into your problem.
