My arm makes steady progress towards normality, but getting it moving again has been like trying to relearn the grammar of another language, one that I should be familiar with, but I can only wield partially. I'm discovering the bend and flex of each muscle and sinew, the turn of the radius as it slides past the ulna, a pair of dancers locked in a limited waltz. I find that by pushing each part just a little more each day, the whole of the arm seems to be coming slowly back to life and lithe. Who'd have thought it would be so difficult to blow one's nose, when you can't get one hand close enough? Or how uncomfortable it is to sleep when you cannot tuck your arm into a supine position?
