Itchy blisters on the fingers may be caused by several conditions, such as atopic dermatitis or dyshidrotic eczema. These conditions are fairly common and are characterized by the appearance of blisters of the sides of the fingers, palms of the hands, and soles of the feet. The small blisters are usually filled with fluid and, once dried, cause the skin to take on a scaly appearance. Additionally, they may not easily visible because they are camouflaged by the thick skin on the fingers and palms. They generally persist for weeks at a time and recur often, causing itching and discomfort.

Common Causes

Although dyshidrosis has no known causes, it is associated with allergic conditions including hay fever, as well as a skin disorder known as atopic dermatitis. Individuals who have nasal allergies may also experience having seasonal dyshidrosis. Other risk factors for this condition include the following:

Stress. Emotional stress can cause veins to break under the skin, leading to itchy blisters.

Exposure to irritants. Certain metals, usually those found as occupational hazards in industrial workplaces, can cause irritations on the skin. These metals include nickel, cobalt, and chromium, to name a few.

Sensitive skin. Individuals who have sensitive skin are at higher risk to develop rashes, especially after coming into contact with substances that can cause irritation and/or allergic reactions.

Atopic eczema. Preexisting skin conditions like atopic eczema may progress into dyshidrotic eczema.

Allergies. Allergic rhinitis, or hay fever, as well as other similar allergies can make a person more prone to developing dyshidrosis.

Moisture. If hands are often exposed to excess moisture, the skin can become irritated, which can in turn trigger the development of blisters and eczema.


The best way to avoid dyshidrotic eczema is to protect the hands from irritants and to keep them dry, especially when using gloves.

There are several options for allergy treatments, depending on the severity and nature of these conditions. These options include allergy shots and other medications that can be obtained over-the-counter or through a doctor's prescription, which are effective in easing discomfort and symptoms of dyshidrotic eczema. These include the following examples:

Antihistamines. Antihistamines are the most common medications used to combat symptoms of allergy. These are often the first to be used when dealing with dyshidrotic eczema.

Leukotriene inhibitors. Leukotriene inhibitors, such as Singulair, are a new kind of medication that are targeted towards minimizing allergic reactions. They work by fighting natural substances known as leukotriene.

Allergy Shots. Allergy shots may work as a more effective solution than pills and other medications. They work in a way similar to how vaccines work - by incorporating a small amount of the substance that causes your allergies, triggering your immune system to make you immune. These shots are designed to make symptoms get better, and if possible, disappear completely.

More often than not, medical treatments meant for skin irritations, specifically dyshidrotic eczema, work effectively and can minimize or even completely eradicate the discomfort and other symptoms that may be brought about by this condition.
