When I have sciatica, like now, one of the most painful maneuvers is rotating in place while lying down. If it wasn’t so cold out, I’d consider setting my tent up.
Or, you could take a page out of 'Face's book and take a sleeping bag to sleep on the floor in the sun room. Or living room. At least there, you could roll over rather than rotate!
And now, for my next trick, I'll be trying to make it to Walmart and back. I love my car!
