Itchy prickly heat rash

Prickly heat, also called [Heat Rash](/conditions/heat-rash/), can cause fine bumps, a prickling sensation, itch, or mild redness after sweating. It commonly affects areas covered by clothing or skin folds, although the exact pattern varies. Scratching may break the surface and make the area more sore. If the appearance is unusual, [Skin Bumps](/symptoms/skin-bumps/) and [Skin Rash](/symptoms/skin-rash/) describe broader symptom categories rather than a confirmed cause.

Cool the skin with a fan or cool damp cloth, shower gently, and pat rather than rub. Change out of sweaty clothing and select loose, breathable layers. Keep nails short and press or tap instead of scratching. Avoid thick, greasy products that seal in heat and avoid fragranced products on irritated skin. If dryness remains after cooling, a bland product used in [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) may be considered. A clinician should guide any [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/), particularly on folds or thin skin.

Seek advice if itch is intense, keeps you awake, returns often, or does not improve after cooling and removing likely irritants. Prompt care is warranted for increasing pain, pus, yellow crust, marked warmth, swelling, fever, or fast-spreading [Skin Redness](/symptoms/skin-redness/). These changes can indicate infection or another inflammatory condition that needs a different plan.
