Focus on the positives. Doctors have to give you all the facts in order for you to give informed consent before they undertake any procedure. This means they have to give the negatives as well as the positives but doesn’t mean that it will necessarily come to that.
Spinal surgery is a complex medical procedure and not without risk, but the fact they are prepared to operate means the medical experts obviously think its worth doing.
Easy for me to say this but remain positive and think of that light at the end of the tunnel which is starting to shine brighter,
