Y'all, my booty butt hurts...

Y'all, my booty butt hurts from a fall I took while skating weeks ago (before I had butt pads).  I read to chill back on activity and let it heal.  I'm like super pretty certain that I didn't break my tailbone.  It only hurts when I move certain ways... like trying not to fall off the hoverboard or when I play with Rose and she suddenly drags me sideways across the yard.  Side-step kind of moves seem to be the worst.

I think I'm not doing the best at resting it aside from actively trying not to be active (hence all of the organization and stuff like the house rather than playing outside on my feet-wheels), but I don't understand why if it's a bone bruise it hurts when my muscles move certain ways.  Are my muscles pulling on it?  What is really going on in my butt-area?  If any of you have any insight I'd love for you to share that with me.

Thanks in advance.  ❤
