This form of urticaria is associated with stress, extreme exertion, heat and sweating.
In this instance the papules and/or wheals that appear are small and pale surrounded by a more red defined area. These are usually 2 -3mm and appear in groups on the upper torso and arms and can ascend to the neck. In some people it also appears on the thighs and arms. As the body temperature rises from exercise or stress the wheals quickly begin to appear. In some cases they take up to an hour to evolve.
Usually the feet, hands, groin and armpits are not involved.
There is a specific reaction in this instance of acetycholine on mast cells and may be related to aquagenic urticaria of wheals and flare ups.
As it seems to be more associated with emotions and stress it is thought to be related to the parasympathetic nervous system(PNS). Usually tingling, burning and itching are associated with it and is thought that histamine has been released as a response to the PNS. The wheals in this case last up to an hour however people can be more severely affected with more acute symptoms.
Headaches, salivating,tachycardia, fainting, breathing difficulties, abdominal cramps and diarrhoea can be a progression though not the norm and even more rarely shock states of anaphylaxis can occur.
It appears more in males than females. It appears to be related to chronic urticaric conditions that are atopic e.g asthma, dermatitis and rhinitis.
