Cholinergic Urticaria

Cholinergic urticaria, a type of hives caused due to raised temperature, often develops while exercising or sweating. The symptoms are wheals, redness around bumps, and itching. In most cases, it appears and disappears on its own. In some cases, it causes exercise-induced anaphylaxis. Avoiding triggering agents is the best way to manage it. Taking antihistamines helps a lot.
