We actually have something that resembles that stool in our kitchen. Thanks, JLx, Meme.

SilverEM mine mag oxide so I will switch.

Yesterday I did some gentle yoga, put a pillow support behind my back and heat pad on my back for hours, had no pain after that. I stretched for nearly an hour before work today and made an effort to keep my shoulder back and not slump forward. I worked on pulling in my abs and having better form. No pain so far.

Hallelujah!!! I'd been contemplating going to Urgent Care, as always LCers know about the body.
