Demographic Uticaria

[Mean_Kitty]

I was dx with Demographic Uticaria.  Seemed to come out of the blue 4 months ago and just getting progressively worse.  I have red tinted skin all over my body 24/7  no relief!!  It also feels sun burnt and sometimes itchy.  I hate it when something bangs against my skin because it makes it itch.  I don't see any raised markings but doctors seem to feel I have dermagrahpic skin.  I can't write my name on my arm etc.....     I have seem 4 derms and 3 allergist.  Everyone is stumped.  I am told there is no cure but to keep taking antihistimines!!!   They do not even work.  Does this sound like Dermagraphic Uticaria??
