I had back surgery.....they shaved the discs of L4 and L5. Even after that I sold my 2010 CVO Street Glide in about 2012 thinking I wasn't going to be able to ride anymore.
Andy kept telling me that I just needed a different set up. Going from the Street Glide back to an Ultra Classic with back rest after a couple of years, I was surprised that I could ride again, for hours, without any back issues. Eventually I bought the 2013 Ultra Classic and matching Bushtec trailer and rode it from Matthews, NC to San Diego in 2 1/2 days without any back issues.
Hopefully you'll experience similar success after your healing. You will need to be much more aware of what you can and can't do and I can tell you that you can't do what you did when you were a 20 yr. old....not even what you did as a 30 or 40 yr. old. Be kind to yourself.....let the youngsters do it! Good luck with it.
Additionally, I drove my F-150 750 miles day before yesterday and 907 miles yesterday without any back issues. I'll be driving another 217 miles today, hooking up my new toy hauler.....a 2021 Grand Design Momentum 21G.....and heading back to Tucson. I'm optimistic that I'll arrive back in Tucson without any back issues.
