I've hurt my left wrist. Whether I stretch out my fingers, make a fist, lift something heavy or just twist and turn it, it gives me pain.
And I'm left-handed, which makes it worse.
Every couple of years I am afflicted with a terrible obsession with one thing or other - and I'll blog about it mercilessly. So if you aren't interested in what I've been saying lately, try again in six months' time.
