Physical urticaria
From Infogalactic: the planetary knowledge core
Physical urticarias represent a distinct subgroup of the urticarias that are induced by an exogenous physical stimulus rather than occurring spontaneously.[1]
The most common form of physical urticaria is dermatographism.[2]
One way of classifying physical urticarias is into thermal, mechanical and cholinergic sources.[3]
