That might not be a bad thing - assuming that it is not anything requiring fine motor skills, but a little lifting and moving of a swollen extremity is supposed to be good therapy - except where blood poisoning is suspected (my fathers family on the female side have a strong association with nursing and midwifery - someone had to stop the doctors killing off the community).
In my continued quest to ignore life's little complications I discovered something neat about extremities, therapy and movement.
About 5 years ago I broke my hand at the base of my thumb, ( whilst playing indoor tennis with a cool 25 year old bass playing goth -long story). Anyway having fallen over I managed to hide the fact that my hand was actually broken for two weeks - didn't want to be stopped going into the pool whilst on holiday. Having finally decided my hand might drop off if I didn't get it fixed, following an extraordinarily painful encounter with a shopping trolley in Waitrose, I ended up with a cast . Still wanting to look cool myself I decided it was perfectly possible to play the recorder whilst wearing a cast and thus did a lot of finger wiggling of the bits that would wiggle.
When they took the cast off it turned out that everything had healed perfectly - my consultant told me that he had been fully expecting the break to need a pin due to my age and the time delay in actually getting it fixed. He was most impressed that recorder playing had worked so well.
From that point on I resolved that wiggling things about a bit when broken was a good plan - and have employed it to good effect on the various other things I have broken since - which are rather more than a woman of my uncertain years should have endured. (note to self - stop competing with 25 year olds- goths or otherwise)
[On reading through this particular diatribe prior to posting, I am rather left wondering in which universe actually playing a recorder with or without a broken hand could be considered cool in any event . oh well ! ]
