duck, I had a 360 fusion at L5 in 2012. I was 38 and had lived with back pain for almost 10 years. The surgery was a success, and I am back to about 95%. I didn't understand how bad my back was injured until everything stopped hurting! Modern medicine is incredible. Don't be scared. It just hurts like hell for about a week.
I don't mind the walk. I love to walk, actually. I just don't want to risk a fall with 50lbs of gear on my back, in the dark, 1-3 miles from my vehicle.
