Sorry to go backwards a bit from the current chat, but....
I used to knit-my mum taught herself to knit left handed (she's a right-hander) so she could teach me. Unfortunately my main problems are now my wrists and neck so I've had to give up, I can't hold the weight anymore
I have exactly the same problem nick, then I discovered knitting socks. You can get some just crazy multi-coloured self-striping wool these days and they're really light to work on.
I found them a bit fiddly to start with, but now my thumb sublux has got worse (ironically improving the function of it), I'm fine. Should be relatively easy on your wrists, as you don't need to make such big movements with the needles as when you're knitting a jumper.
Plus there's the added bonus of having short projects, so you can have a finished pair of socks faster than a jumper and not necessarily have to abandon the work for weeks at a time if you hit a bad patch.
