Heat rash in the elbow crease: what to know

The elbow crease is a sheltered bend where sweat and rubbing can remain against the skin. Heat rash may look like small prickly bumps with redness, while eczema often brings dryness, scaling and recurrent itch. Cracking, oozing, crusting or marked tenderness can suggest a different problem. Skin Rash and Skin Redness descriptions can help your clinician assess the pattern.

After washing, pat the crease dry rather than rubbing it. Wear loose sleeves, take breaks from heat and change damp clothing. Avoid fragranced products and thick occlusive layers while bumps are active. A clinician can recommend a suitable bland moisturiser or Emollient Therapy; Topical Corticosteroids may help selected inflammatory rashes but should not be used casually on broken or infected skin.

Book medical advice if the area is cracked, weeping, rapidly expanding, very painful, hot to touch or associated with fever. Seek urgent help for facial swelling, breathing difficulty or faintness. Recurrent changes in the elbow crease, especially with thick scale or persistent Skin Bumps, deserve diagnosis rather than repeated treatment for presumed heat rash.

Does the appearance fit heat rash or flexural eczema, and should I use a moisturiser, steroid or another treatment? How can I keep the crease dry without irritating it?
