I’ve got some kind of RSI – pressure on a nerve in my neck makes my left arm numb (I’ve pretty much ruled out a stroke). My neck hurts and I can’t pick anything up (although my 28Kg son begs to differ). I’ve sort of fixed my stupid working posture and now I’m just waiting for it to get better. In the meantime, these things don’t work. They’re supposed to be mega-painkillers but they give me about an hour of relief maximum. This would be fine except I’m supposed to take them every eight hours. Worst of all, I think this might be a blogging injury. Incidentally, if you search for the words blogging injury at Google, you’ll learn quite a lot about Robert Schumann’s perplexing 1832 injury to his hand, caused by a ‘home-made mechanical contraption’ designed to strengthen his hands. The injury prevented him from becoming a concert pianist.
