What should you know about an inflamed sweat rash?

Heat rash, also called prickly heat or miliaria, develops when sweat ducts become blocked and sweat irritates the surrounding skin. It may cause small bumps, redness, prickling, itching, or a stinging feeling, especially in skin folds, under tight clothing, or after heat and exercise. Scratching can break the skin and invite infection. The pattern can resemble other causes of Skin Rash, Skin Bumps, or Skin Redness, so persistent or unusual symptoms may need examination.

Move to a cooler space, rinse gently with lukewarm or cool water, pat dry, and wear breathable loose clothing. Avoid heavy ointments, perfumed products, hot showers, and activities that leave the area sweaty until it improves. Do not scratch; keep nails short if itching is strong. An Emollient Therapy plan may help when the surrounding skin is dry, while Topical Corticosteroids should be used only with suitable medical guidance because the rash location and cause matter.

Seek medical advice if the rash is spreading, very painful, oozing, crusted, or not improving after cooling and gentle care. Fever, marked swelling, pus, or feeling unwell needs prompt assessment. Get urgent help for breathing trouble or facial swelling after a product. Babies, people with significant illness, and anyone with a rash involving the eyes or mouth should be assessed sooner.

Is this heat rash or another skin condition? Should I use a moisturiser or medicine, and which ingredients should I avoid? How can I prevent recurrence in this climate or during exercise?
