Symptomatic dermatographism- how did i get this skin problem!?

Nobody knows.: Dermatographism is a form of hives (urticaria). The hives develop in response to rubbing or scratching the skin, which releases histamine, which in turn causes the hives. Why some people get this response to physical rubbing of their skin is not known yet.
