Good thoughts sent your way Dave! Please get back to us when you can so we know you're ok. Pulling for you man and will pray that all goes well.
My dad was presented with the same operation....he was afraid of the bad part possibly happening...so he's stayed on meds. They put it out to him saying "if it works, you'll feel like you're 20...if it doesn't...." You know the drill there.
I put him on a diet and it really is amazing how much it's helped his back. 20 lbs off your frame can definitely make a difference....not to mention he's diabetic so removing the bad food helped there too and it has also kept his sugar consistent. Anyone with back issues that can lose a little weight...it will definitely do some good if you can diet.
