While I've never had back surgery, I've had major surgery in 2006 for lung cancer. Never once did I worry about it as I had put 100% faith in my surgeon whom I met many times before the surgery date.

The one thing I learned was to not waste energy worrying needlessly. Instead, pre-surgery, I focussed on being as healthy as I could be at the time so that post-surgery recovery would be much faster.

Breathe deeply and know that everything will go well. I have it from the source, Merlin. He tells me that you will be surprised on how well you do.
