Chet,
If you are having your back scoped, you will do fine. I have had both a scoping and a cut job. I was pain free from the moment I woke up from both surgeries. The reason for the 2nd scope was for some scar tissue, no biggie at all, as a matter of fact, i wasn't even out for it, just a local.
Both times My re-hab was the neighbors hot tub after a week or so of Ice. When your lower back muscles get tired, they will cause more pain then the actual injury. A hot tub will help those puppies relax and reduce nerve tension pain.
I will also recommend lots of ICE for the first week or so. This is the only thing that will cut the normal swelling that happens after surgery.
After a couple of weeks, exercise, lite walking, then more to build up endurance. Hopefully your Doctor has some type of Sports Medicine backround, the sports type recovery seems to be more effective for the long term .
Don't fret what you can't control, good luck, and we will see you on the road.
Ride safe all, ands please, ATGATT.
