I get the MRI done -what a weird experience, being stuck inside a metal tube for half an hour with Thor striking his anvil just beside your head. Glad when it’s over
Then the Lumbar Puncture, in which cerebrospinal fluid is taken from your spine. Not nice at all …it took three separate lots of Doctors to get it right. They were all lovely, but it was tiring and somewhat painful despite local anaesthetic. And all for a tiny amount of the fluid, which looks for all the world like water.
