I am sorry you are going thru all this. I have a sliding hernia and bend at the knees when something has to be picked up. that has helped me because my trunk/head stay upright enough to prevent problems. If you haven't tried that you may want to and see if that does the trick for you. You can also try "grabbers" if all you want to do is pick up something light (people usually use those to grab stuff off high shelves). There may be other options. For instance, I use a picker-up suction cup at the end of my pickleball paddle so I don't bend over to pick up a ball. Good luck!
