General
Heat rash, also known as prickly heat or miliaria, is a common skin condition that occurs when sweat becomes trapped within the skin's surface, leading to small, itchy, and sometimes painful red bumps or blisters. It typically occurs in hot and humid weather conditions or when the skin is covered with tight clothing that hinders proper ventilation.

Signs & symptoms
The primary symptom of heat rash is the appearance of small, red, and itchy bumps on the skin's surface. These bumps may feel prickly or cause a stinging sensation. In severe cases, the rash can lead to the formation of small blisters.
Diagnosis
Heat rash is usually diagnosed based on its typical appearance and the presence of symptoms. A physical examination by a healthcare professional is often sufficient for diagnosis.
Treatment
Treatment for heat rash involves keeping the affected area cool and dry. Measures such as staying in a cool environment, wearing loose-fitting clothing, and avoiding excessive sweating can help alleviate symptoms. Calamine lotion or over-the-counter hydrocortisone creams may also be used to soothe itching and inflammation.
