I have dermotagraphia.

I have had it for about a year now and was wondering if any one else has it on here. http://en.wikipedia.org/wiki/Dermatographic_urticaria
I hate it. It was going good in the winter but now I am getting really itchy and sweaty from all the heat. This is made worse by my allergies flairing up. Share with me your thoughts or ideas or shoot me some questions.
