Heat rash that will not go away

Heat rash usually follows sweating and friction, but a lingering eruption can have a different explanation. Contact dermatitis from detergent or skincare, eczema, folliculitis, fungal irritation, and bacterial infection may all cause bumps, redness, itch, or soreness. Note whether the area is spreading, whether new products touch it, and whether the surface is scaly, wet, crusted, or painful. Those details help a clinician compare heat rash with other Skin Bumps or Skin Rash causes.

Keep the area cool, clean, and dry; wear loose clothing and wash reusable garments after sweating. Stop newly introduced fragranced products and avoid thick occlusive creams unless a clinician recommends them. Do not scratch, squeeze, or use leftover antibiotics or steroid mixtures. A bland moisturiser can reduce dryness; Emollient Therapy offers more information. If a clinician confirms inflammation, they may discuss Topical Corticosteroids and how to use them safely on that body site.

Book an assessment when the rash persists despite sensible cooling, keeps returning, or is difficult to identify. Seek prompt care for pus, yellow crust, increasing warmth, severe pain, marked swelling, blisters, fever, or a rapidly expanding area. Urgent help is appropriate if you feel seriously unwell or the rash involves the eyes or mouth.

Ask what diagnosis best fits the appearance, whether a product or medicine may be maintaining the irritation, and whether testing or a prescription is needed. Tell the clinician when it began, what cooling measures changed, and every cream or cleanser used on it.
