Will be thinking of you James, I hope that it isn't too sore.
My advice would be homeopathic arnica tablets. Nelson's homeopathic arnica 30x
My Dad broke his back a few years back in France and I sent him some. It is used as a mainstream medicine there and even though he would never normally use anything like it, he took it to keep my quiet and then commented on how quickly he healed and that the nurses thought that the arnica had been very useful.
I apologise if i'm preaching to the converted.
Anyway take care and I hope you do manage to enjoy a bit of rest and don't fret about the undone chores too much.
