Small itchy bumps like heat rash

Small, itchy bumps resembling heat rash are usually caused by conditions such as miliaria (heat rash), eczema, or allergic dermatitis. Treatment should be selected based on the specific condition. Detailed analysis is as follows:

1. Miliaria (Heat Rash)

This commonly occurs in summer and is related to sweat irritation. Patients may develop red or skin-colored papules on the skin surface, accompanied by symptoms such as itching and prickling pain. In such cases, topical medications such as calamine lotion or desonide cream should be used according to medical advice.

2. Eczema

Eczema is associated with external environmental irritants, allergies, and other factors, leading to inflammatory changes on the skin surface. It manifests as a rash similar to heat rash, often accompanied by local oozing, erosion, and itching. Patients can use topical medications such as tacrolimus ointment or halometasone cream under medical guidance.

3. Allergic Dermatitis

If an individual has recently come into contact with an allergen, a localized allergic reaction may occur, resulting in a rash resembling heat rash. The affected skin may appear red and swollen, accompanied by itching and local warmth. In such cases, patients should take oral antihistamines such as levocetirizine hydrochloride tablets or loratadine tablets as directed by a physician.

Besides the common causes mentioned above, other possible factors include contact dermatitis, tinea corporis (ringworm), urticaria (hives), etc. Patients should seek timely medical attention. During treatment, proper skin care is essential, and excessive scratching should be avoided.
