Update on the wrist is that - wait for it - I have gout! Well, a form of gout in as much as the problem is a build up of crystals in the joint causing restricted movement and inflammation. Caused by a build up of uric acid in the body, these crystals can apparently attack any joint, not just the feet, and can also affect the kidneys, hence kidney stones.
The good news is that the pain is now bearable, the swelling has gone down and hopefully the crystals can be dispersed with medication. Bad news is that I can't use my hand properly without the support, and this coupled with instructions to 'rest' the joint means still no sewing, but in comparison with all the other problems happening around the world, things aren't too bad really.
Glorious Spring sunshine has meant that even though my quilting passion can't be fed at least my other favourite pastime, walking, is keeping me sane :-)
