Why would extreame pressure relieve pain?

OBBN, you might have tried this already, but when I have flare-ups of lower back pain I’ll sometimes lie on my back with a tennis ball or baseball positioned where the pain is. The weight of my body presses me down on the ball enough to get some relief. Sounds like your pain is much worse than mine but…FWIW.

I haven’t tried that yet, but will on the next flare up. Thanks
