Tailbone/coccydinia pain

[DarlingMe]

I know this is kind of a common thing but I am having difficulty finding any relief from it. It is pretty much constant. Tried the heating pad, I have had training on "lifting mechanics", and sleep with a pillow b/t my legs. I am looking for some stretches to see if they will help. I cannot find any online.

Has anyone had this before or know where I can find some home physical therapy treatments or exercises? The ones for sciatica and SPD dont seem to do the trick.
