What Causes Itchy Small Blisters on the Fingers?

Itchy small blisters on the fingers suggest that the patient has an inflammatory skin condition. There are many possible reasons for the appearance of small blisters on the fingers.

It could be vesicular eczema of the hands, which occurs when the hands are frequently exposed to physical or chemical irritants such as hot water, soap, laundry detergent, or dishwashing liquid. Patients in certain occupations may often come into contact with machine oil or chemical reagents, leading to skin allergies on the hands. It might also be dyshidrotic eczema (pompholyx), a recurrent blistering disorder affecting the palms and soles with unknown cause. This condition is often associated with excessive sweating of the palms and soles and is currently considered to be a type of eczematous rash triggered by various factors. Another possibility is vesicular tinea manuum, a contagious fungal infection caused by superficial pathogenic fungi affecting the skin of the palms and fingers. Skin lesions typically occur on the palm, web spaces between fingers, or around rings on fingers where jewelry is worn.
