Thank you for your replies.
I'm at a loss at the moment as to what to think.
I started out with a simple MRI on my back as this was thought the main culprit. As I have had problems there and surgery twice, and further I juries to c spine and thoracic spine I just thought it would be a case of disc trouble, physio etc
Due to my already having had spinal issues and a brain injury they want to do as much testing as possible to see what is residual from previous injury and what could be causing my symptoms.
The Dr said it is sounding like an auto immune thing, possibly PN or maybe something else but wait and see what the tests show up.
I am rubbish at waiting!
