What causes small bumps on the body accompanied by itching?

Small, itchy bumps on the skin are usually caused by conditions such as eczema, urticaria, or allergic dermatitis. Specific details are as follows:

1. Eczema

Eczema is an inflammatory skin condition associated with exposure to allergens, environmental irritants, and other factors. It may lead to the appearance of skin-colored or red papules on the skin surface, accompanied by symptoms such as itching, stinging, and oozing. It is recommended to follow medical advice and apply topical medications such as budesonide cream or halometasone cream to alleviate symptoms.

2. Urticaria

Consuming large amounts of seafood such as fish or shrimp may trigger urticaria, resulting in small bumps or red patches on the skin, often accompanied by itching, swelling, and other discomforts. Patients should take antihistamines such as loratadine tablets or chlorpheniramine maleate tablets as directed by a physician for treatment.

3. Allergic Dermatitis

If a patient has recently been exposed to an allergen, an allergic reaction may occur on the skin, leading to papules along with symptoms like itching and warmth. In such cases, medications such as calamine lotion or compound acetic acid dexamethasone cream should be used under a doctor's guidance to relieve symptoms.

In addition to the common causes mentioned above, other conditions such as tinea corporis (ringworm) may also be responsible. Patients should seek timely medical evaluation and receive treatment based on the underlying cause under medical supervision.
