Fingers have many small bumps that look like tiny blisters, but are not itchy.

Small granular bumps resembling tiny blisters on the fingers that do not itch may be caused by conditions such as dyshidrotic eczema, eczema, or tinea manuum. Treatment should be targeted according to the specific cause. Detailed analysis is as follows:

1. Dyshidrotic Eczema

Dyshidrotic eczema is characterized by the appearance of widespread small blisters on the palms, soles, and between the fingers, ranging in size from pinhead to grain-of-rice. The blister fluid is clear, and early stages may not involve itching, often accompanied by excessive sweating of the hands and feet. Symptoms can be relieved under medical guidance with topical applications such as calamine lotion or pimecrolimus cream.

2. Eczema

Eczema is an allergic hypersensitivity reaction. When it occurs on the fingers, local skin usually shows varying degrees of damage, such as redness, papules, and small blisters. These blisters may not cause itching. Under a doctor's advice, topical medications like desonide cream or hydrocortisone butyrate cream can help alleviate symptoms.

3. Tinea Manuum (Fungal Infection of the Hand)

Tinea manuum refers to fungal infection affecting the skin of the fingers, palms, or backs of the hands, primarily transmitted through contact. It may lead to symptoms such as small blisters, erythema, and papules at the affected site, though some patients may not experience itching. Relief can be achieved under medical supervision using topical antifungal agents such as compound clotrimazole cream or amorolfine hydrochloride cream.

Besides the above relatively common causes, other possible conditions include contact dermatitis, herpes infections, palmoplantar pustulosis, etc. If any discomfort or symptoms occur, prompt medical evaluation and treatment are recommended to avoid disease progression.
