Is there a difference between heat hives and hives?
A doctor has provided 1 answer
Yes: Urticaria, "hives" are itchy, raised red bumps that typically move around from one skin site to another and last less than 24hrs in one location (hives can occur daily, but typically come and go). Cholinergic urticaria "heat hives" are hives that occur when the body is overheated by exercise. Raising the body temperature more than 0.7 degrees (hot bath) may be sufficient to trigger "heat" hive.
