Behold, the Human Etch-a-Sketch!
I occasionally suffer from Dermatographic Urtecaria, which is basically a different way of phrasing "Odd skin allergy". I'll randomly get a histamine build up in my blood which when the allergen makes contact with my skin causes all of it to bubble up in the one spot under my skin, and stay there for about half hour. It used to burn at first, but after a few weeks I got used to it and it now doesn't bother me at all.

So why does this make me special? I can only trigger it willingly on my arms. So much so that I can actually draw and write on my arms out of histamine "hives". Fuck me when I discovered I could do this I felt like an X-Men, but on a limited budget.

But what's the point of having super-powers if you can't share it with the townspeople? First thing I did was I went into the office wearing a short sleeve shirt and sat within sight of the office arse-licker. I wrote a few letters on me arm, and the histamine took effect...

An hour later when he reported me to a manager for calling him a cunt by writing it on my arm I sat there with blank arms looking at him as if he was a right odd-bob, and the manager looked oddly at the cunt too. Result!

This does seem quite odd....
... how do you "write" on yourself - do you actually touch the skin or do you just visulaise it? Or indeed something else entirely?

I used to be able to do this
I could write on my forearms by gently scratching with my fingernails and the letters would pop up like poppy uppy things. It used to cause great amusement amongst my friends. I can't do it anymore though.
