Extreme dyshidrotic eczema: what to know

Dyshidrotic eczema produces clusters of deep-seated fluid-filled blisters, commonly on the sides of fingers, palms, toes or soles. The skin may burn or itch before blisters appear; after they dry, peeling, soreness and fissures can interfere with walking or using the hands. Irritants, sweating, stress, metal exposure and other eczema patterns may contribute, but a similar-looking rash can have another cause. [Dyshidrotic Eczema](/conditions/dyshidrotic-eczema/) provides condition-specific context.

Use cool compresses for short periods, wash gently and pat dry. Avoid bursting blisters, fragranced products, harsh cleaners and prolonged wet work; wear protective gloves with a soft cotton layer for necessary tasks. A clinician may prescribe [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) for inflammation. Severe or recurring disease may lead to discussion of [Narrowband UVB Phototherapy](/treatments/medical-dermatology/narrowband-uvb-phototherapy/). Keep cracked areas covered with a clean dressing and seek advice about work or footwear changes.

Arrange review for painful, extensive or recurrent blisters, inability to walk or use the hands, or cracks that do not heal. Seek prompt care for increasing warmth, swelling, pus, honey-coloured crusting, red streaks or fever, which can signal infection. New [Skin Blisters](/symptoms/skin-blisters/) or persistent [Itchy Feet](/symptoms/foot-itching/) should be assessed when the cause is uncertain.

Ask whether the eruption is dyshidrotic eczema or another blistering condition, how to use prescribed steroid treatment safely, which irritants to avoid, and when light treatment or further testing is appropriate.
