What is a cholinergic urticaria?

ANSWER

You can get itchy red hives on your skin for lots of reasons. The ones that break out when you're sweaty from a workout, nervous, or just hot are called cholinergic urticaria (CU).

They're caused by nerve fibers in your sweat glands. Your skin reacts to the heat and sweat when your body temperature goes up.
