A member asked:

How come i get hives on my arms and behind my knees after i run?

A doctor has provided 1 answer

Sweat induced hives: It is fairly common to see people develop hives with exercise, hot showers or with anxiety. Basically anything which causes sweating. The medical term is cholinergic urticaria (hives). Fortunately it can be treated with antihistamines.
