I have a similar issue, DDD, being tall with a Buddha belly doesn’t help either 😅.
I got an inversion table and that helps relieve the pressure, that’s about the extent I am willing to go. When I am dealing with my back, letting someone start cracking and twisting me does not sound like a good solution, one wrong move and you’re paralyzed. Same reason I won’t go under the knife to have my disks fused.
I do have a trick that may help you, it got me through many days at work when I didn’t think I could stay standing. Take a tennis ball and put it between you and a wall and start moving up and down until you get it in the right position, then just start going up and down. It’s not a permanent fix but it may get you through those embarrassing moments.
