Dyshidrotic eczema (pompholyx) is a skin condition that mainly affects the hands and sometimes feet, causing it in these areas due to sweat glands, irritation, stress, and allergies. It appears as small itchy blisters on the palms or fingers, which later lead to redness, peeling, dryness, and cracking during healing. Flare-ups usually come in cycles and last a few weeks. Treatment includes steroid creams, moisturizers, and antihistamines for itching, while prevention focuses on avoiding irritants, reducing stress, using gentle soaps, and keeping hands protected and well-moisturized.
