Many people with the condition also suffer from dermographism and cholinergic urticaria.

EU can be differentiated from cholinergic urticaria by the hot water immersion test.

Occasionally, cholinergic urticaria may be associated with systemic symptoms such as fever and/or difficulty breathing.

Cholinergic urticaria or sharp pain over the entire body induced by elevated body temperature was reported in 32 cases (50%).

This differentiates EU from cholinergic urticaria.

Cholinergic urticaria (CU) is one of the physical urticaria (commonly referred to as hives), provoked during sweating events.

Exercise urticaria and anaphylaxis can be categorized as cholinergic urticaria or exercise-induced anaphylaxis based on the clinical manifestation.

Someone with EU will not develop hives, while a person with cholinergic urticaria will develop the characteristic small hives, especially on the neck and chest.

Cholinergic urticaria (CU) is one of the physical urticaria which is provoked during sweating events such as exercise, bathing, staying in a heated environment, or emotional stress.

Though overall research is limited, various studies indicate that Cholinergic Urticaria is relatively common across populations with prevalence rates reportedly ranging from 5% to 20% (depending on locale, race, and age).

Finally, cholinergic urticaria, or urticaria induced by heat, can occasionally appear to be solar urticaria because the heat from the sun will cause a person with the disease to have a reaction.

Physical Urticaria, Cholinergic Type None Cholinergic urticaria is a relatively common disorder of the immune system characterized by an immediate skin reaction (hypersensitivity) to heat, emotional stress, and/or exercise.

The symptoms of cholinergic urticaria may develop due to the reaction of specific immune system antibodies (IgE) to certain antigens, leading to a hypersensitivity response (Type I) and the wheal-and-flare reaction that is typical of cholinergic urticaria.
