Thanks for the tips :-) From what my H says...it's not that his back is extremely painful, it's more of a nuisance than anything else right now. I know mentally...it's wearing on him to not know what the problem is though, which he's hopefully going to find out today.
The kidney stones, from what he says are what's really bothering him right now.....the not passing of them yet. It's like he's expecting this horrible pain to hit anytime (and he's dreading it, which I completely understand) and he doesn't want to be caught in the middle of something like ML when that pain hits again.
Now, since he does have some physical maladies going on right now...I'm able to be understanding. We're getting ready to have a conversation though about him getting comfortable using our "toys". We're at a point now where I believe this can be introduced effectively and he'd be open to it. So it's time to take advantage of this opportunity for us to broaden our horizons just a bit more.
