Things going very wrong after Dynesys

[LC in UK]

Spinal probe is a tiny camera into the spine through an incision in the lumbar area whilst you are sedated but not fully "out".
They can also deliver anti-inflammatories or steroids at the same time apparently and the whole thing is also done with some kind of radiological guidance.
Had this procedure done twice before prior to surgery so surgeon has a very good idea of whats going on.
