Here is my hand at present - 3.5 weeks after the operation. You'll see the j-shaped scar on the thumb where it was opened up. You can't tell from here but the thumb is badly swollen. I have very limited movement in that area and it's uncertain how much I'll get back.
My console gaming career is therefore over, and the Xbox 360 is on ebay. I'm not too bad at warcraft, since I don't use my left thumb to play. I have signed for a raid on Tuesday, which will probably be my first instance since the accident. Will see how it goes.
