This week, I have been suffering from a full-blown case of desk-contact-dermatitis (don't laugh!). Yes, that's a skin condition that has been created by the constant friction of resting the side of my arm on my desk. It went from rosy pink and a little scratchy to bright red and freakin' itchy! Hubby (who trained as a doctor) asked me: if you feel it getting sore, why do you keep putting your arm on the desk like that? To which I replied: I dunno.
That's not all. Sometimes I sit on the chair so much that my butt and upper thighs literally throb when I get up at the end of the day -- even when I do go for a run at lunch. I'm not sure I ever had this problem in my office life (possibly because I was usually fabricating excuses to go 'consult' (read: gossip with) my colleagues).
And of course there's the inevitable writer's arse. Although strictly speaking I'm not sure that could be called an injury, it's definitely a liability!
What injuries have you suffered from your writing? Please don't tell me I'm the only one!
