What should you know about water blisters on hands and feet?

Dyshidrotic eczema causes intensely itchy, deep-seated blisters, commonly along the sides of fingers, palms, toes, or soles. The blisters can dry and leave peeling, cracked, or tender skin. Heat, sweating, irritants, and stress may coincide with flares, although a clinician may need to exclude infection, contact dermatitis, or another blistering problem.

Use lukewarm water and a fragrance-free cleanser, pat dry, and apply a thick moisturiser after washing. Wear protective gloves for wet work, with a soft cotton layer if needed, and choose breathable footwear. Do not burst the blisters or scratch them; broken skin can become infected. A clinician may prescribe topical corticosteroids, and persistent disease may need other options such as narrowband UVB phototherapy.

Arrange an assessment if itching disrupts sleep, cracks are painful, walking or hand use is difficult, or episodes keep returning. Seek prompt care for spreading redness, warmth, pus, fever, or rapidly worsening pain. A review is also useful when blisters affect only one area or follow a new chemical exposure, because the treatment may differ.

Ask whether the pattern fits dyshidrotic eczema, which irritants to avoid, how to use prescribed cream safely, and what to do when the skin cracks.
