Pictured above is Sarah Beal, a 43-year-old mother-of five has Dermatographia (a rare skin condition allows her create patterns and pictures on her own skin and watch it disappear like an Etch a Sketch within an hour).
Sarah Beal who is from Arley, Warwickshire, discovered her dermatographia just three years ago. She said:

'But as it got worse I knew something wasn’t quite right. I could give my back a scratch and before I knew it my skin would turn red and be really painful.
'Eventually I Googled the condition and I just couldn’t believe it.'
