I have already been down that path. Over the last year I have had 2 MRI scans, 2 CT scans and 2 EEGs and a spinal tap. There has been no significant changes (whatever that means) over the last 10 years. Other recent x-rays and bloods etc have shown up kidney stones, polymyalgia rheumatica and temporal arteritis, but that's about all.

They acknowledge there is some undefined neurological problem - I have presented with fixed and dilated pupils, muscular weakness on one side, lack of balance etc, but nothing shows up that can explain the symptoms.

I often get the feeling that the neurologists think there's some minor neurological problem contributing to my condition, but most of it is psychological, while the psychologists and psychiatrists think there is some minor psychological condition present, but most of it is neurological.

It would be nice if all my symptoms fitted neatly in one basket, but I realise that's asking for too much
