Today I had brain scan and an MRI of my entire spine, this meant lying prone in the MRI machine for almost 2 hours -not very relaxing. I was then sent off to the London Bridge Hospital for a lumbar puncture. This was the worst test of all was the Dr. had four or five attempts at pushing the needle through my spine in order to extract some spinal fluid. Resting after that was necessary for two to three hours but this did not stop me suffering a severe headache which kept me in hospital overnight. Even after two sleeping pills and a diazepam I only managed one hour 40 minutes sleep. Fortunately there was a good television in the room so I was able to keep myself amused during the night.
