Which condition is described by a red, raised rash with prickling sweat?

• A. Heat Rash (Prickly Heat)
• B. Heat Syncope
• C. Exertional Heat Exhaustion
• D. Exertional Heatstroke

Answer: (A)

Heat rash occurs when sweat ducts become blocked in hot, humid conditions, causing a red, raised rash with a prickling or tingling sensation as sweat gets trapped under the skin. This prickly, irritated feeling and the localized rash fit the description given. It's typically limited to areas where sweat collects or where clothing traps heat, rather than involving systemic symptoms. In contrast, heat syncope is fainting or dizziness from heat and dehydration without a skin rash. Exertional heat exhaustion presents with generalized heat stress signs such as heavy sweating, fatigue, weakness, nausea, and a higher heart rate, with skin that is moist but not a localized rash. Exertional heatstroke is a medical emergency characterized by altered mental status or unconsciousness and a core temperature well above normal, with skin that can be very hot and either dry or moist, but again not just a red raised rash with prickling sensations. So the description best matches heat rash, also known as prickly heat.
