Thank you, this is good information as I am trying to eliminate possible causes as to date there seems to be no identifiable causes for my PN. I had an MRI on lower back last week and haven’t got results but my GP doesn’t think it will show up anything, again eliminating process. All this info will be going to the neurologist I will seeing in a week or so.

I am not hopeful that I will come away from Neurologist with anything helpful.
