I have Dermographism which is a type of urticaria, its a strange one though as nothing is known of its origin or what causes it. Something just has to touch my skin lightly and the skin turns to raised welts, i can draw pictures on my skin lol it is so itchy its unbearable. i take my tablets all the time but if im sleeping and the tablets wear off i am woken by the adrelalin that starts to pump again to counteract the reaction!!
It is so hateful. i have to take special antihistamines everyday, its the only thing that makes it go away because it is like an allergic reaction, only not!! as histamine kicks in to stop you going into anaphalectic shock.
I got it out of the blue, i couldnt find very much about it though thankfully my doc knew what is was, that was three years ago and nobody knows how long it will last.
And more people are getting it....
