As summer approaches, many look forward to sunshine — but for some, the heat brings back the discomfort of eczema flare-ups. One particularly troublesome type is dyshidrotic eczema, which causes “tiny, fluid-filled blisters” on the hands and feet that can be “incredibly itchy and painful.”

Also called pompholyx, its exact cause is unknown, though experts believe it’s linked to an overactive immune system and can be triggered by “allergens, irritants, or even stress.”

It usually affects adults between 20 and 40, with women more prone than men. Those with a history of eczema, hay fever, or other allergies face a higher risk.

Warning signs include “painful red bumps,” intense itching, and sometimes a burning feeling. Over time, the skin “may become thickened and cracked,” especially if untreated.

While there’s no permanent cure, managing triggers and using medical treatments can control symptoms. Moisturizers, topical steroids, and avoiding irritants can bring relief and help prevent flare-ups, making the warmer months more comfortable for those living with this chronic condition.
