Back pain is so awful...mine can be pretty bad sometimes. We got a new queen mattress about a month ago and I am just starting to feel like I've adapted to it and am not getting up in much pain any more. Ours is a very dense memory foam and that takes a while to get to the point where it adapts to your shape and pressure points. Latex is worse, I understand but I don't know what you have.

I'm glad it wasn't a wheel bearing...that's SO expensive I can say from experience.
