'Twere the coccyx what took the brunt

Last night it froze very hard, this morning we woke up to rain. We were going to visit our daughter and grandsons. From the front door to the drive there are 2 steps.
You all remember that I christened the back steps by falling down them in the summer? well I've done the same today . The steps had ice under the rain which we didn't know. Mr Mog had already been out the door a couple of times and no problems. I apparently found the only bit that was slippy:(
I landed firmly on my rear, specifically the coccyx. It is probably some consolation that I'm not a skinny person, the padding helped I think.
But I am in a lot of pain, dosed up on various things, covered in arnica frequently and can't sit too long or lie down for long. Worst pain I have had in a long while.
I don't like steps or stairs, at all.
