Sacroiliac Joint Cushions
I've been in agony for a very long time. They finally did a fluoroscopy guided steroid injection which barely scratched the surface, but the numbing compound definitely worked temporarily. Now I have the area, I've been working on making it happy. Most effort seems to be dampening vertical vibrations, but I can literally feel the house shake in the XY axis. I need it disconnected, some telescopes float on oil like the Sofia. I thought the slack in a turntables would be enough or the sliding mechanism in car seats, but I found something better. I have polypropylene house wrap, from the orange apron, for light blocking experiments. So I stacks 3+ sheets inside an $5 Ikea seat cushion and it hit the spot. I've also stacked them under the feed of my bed too. The layers cannot be connected, so you can't just fold it.
