I'm doing a bit better with my hands, since I've been wearing wrist splints at night I can actually sleep again and now have some definite news to share at last. :-)
I went through to the big hospital in Aberdeen on Monday and had a full set of tests. I've been scanned, electrocuted (*in small doses!) and had pins stuck into me. The 'electrucution' was part of a Nerve Conduction test - layman here describing just what I watched and sort of understood. They check for the nerve responses in each finger and from several different points on the hand. By reading the electric current feedback they can tell where the nerves are blocked or damaged. It wasn't painful, more like fizzy electric shock... like this in your hand and fingers.
Typing is better, but still not something I can do for long so I'll have to stop now.
My love and best festive greetings to all
