Generality
Cholinergic urticaria is a skin disorder that occurs in response to a hot thermal stimulus and therefore does not depend on allergic causes.
It is quite common for patients with cholinergic urticaria to also suffer from other forms of physical urticaria, sometimes triggered by stimuli of the same nature. Therefore, it is not impossible that a patient with cholinergic urticaria could suffer from cold urticaria, pressure urticaria or aquagenic urticaria at the same time.
Treatment of cholinergic urticaria - although in some cases it is not necessary - involves the administration of antihistamines. However, as with many other conditions, prevention remains the best cure currently available.
