Small blisters on hands and body

Small blisters appearing on the hands and body are usually caused by conditions such as eczema, allergic dermatitis, or contact dermatitis. In such cases, patients should seek timely medical evaluation and treatment. Specific causes are analyzed as follows:

1. Eczema

Eczema is a common inflammatory skin condition, often associated with excessive sweating or exposure to allergens. It can lead to the development of papulovesicular lesions, accompanied by symptoms such as oozing and erosion. Patients may use medications like desonide cream or tacrolimus ointment under medical guidance to alleviate symptoms.

2. Allergic Dermatitis

Allergic dermatitis is typically related to decreased immunity or exposure to allergens. It commonly manifests as skin papules or blisters, accompanied by swelling, warmth, and itching. Patients should follow medical advice to take antihistamines such as chlorpheniramine maleate tablets or levocetirizine hydrochloride tablets for treatment.

3. Contact Dermatitis

Contact dermatitis is a skin reaction triggered by direct contact with external substances. Patients often develop vesicles or papules, along with symptoms like itching and soreness. Under medical supervision, topical treatments such as mometasone furoate cream or hydrocortisone butyrate cream can be applied to relieve symptoms.

Besides the above common causes, other conditions such as herpes simplex, herpes zoster, or fungal infections may also be responsible. Patients should avoid scratching the affected areas to prevent skin damage and promote proper healing.
