Hey, Sandy, I can empathize with Jim's butt just a bit. When mine gets to me, I kind of build up some pillows under the small of my back and under my thighs so it can rest with less contact.

It's like that hemorrhoid donut thingy concept. I'm wondering if you could set Jim up with some thick material, cut a hole in it for his butt region and have him lie on it for a few hours each day. Between that and the standing machine, he might get some relief.

Also, if any of his sheets or undergarments have synthetic materials in them, you might try pure cotton for awhile.

Finally, I have found more great uses for hand sanitizer gel, I swear by it, even for my pierced ears and my fat girl belly button! Beware, though, it smarts but good if the skin is raw!
