Itchy Bumps That Look Like Mosquito Bites but Aren’t

Hives often form smooth raised areas that shift or fade, whereas eczema tends to be dry, rough, or cracked. Contact dermatitis follows exposure and may match the shape of a strap, jewellery, cosmetic, or plant. Scabies can cause intense itching at night and affect several people sharing a home. A yeast infection favours warm, moist folds and may have small surrounding spots. Psoriasis and lichen planus usually have more persistent, characteristic surface or colour changes.

These are clues, not a diagnosis. Record when the bumps began, where they appeared first, and whether each lesion lasts briefly or remains in place.

Stop recently added fragranced products and use a gentle cleanser with a plain moisturiser. Cool the area rather than rubbing it, and keep nails trimmed. Avoid borrowing or sharing clothing, towels, and bedding until an infestation has been considered. Do not layer several medicated creams: the wrong product can mask the pattern or irritate the skin. A clinician can select treatment after examining the distribution and surface.

Book an assessment for a rash that persists, spreads, repeatedly returns, affects sleep, or involves other household members. Seek prompt care for fever, rapidly increasing pain, pus, marked warmth, blistering, or facial or eye involvement. Emergency services are needed for breathing problems or swelling of the mouth or throat.

Ask whether the rash resembles hives, eczema, contact dermatitis, scabies, psoriasis, or infection; whether anyone else needs assessment; and how long to try the recommended treatment. Show dated photographs if the bumps change before the appointment.
