Oh my ShootingStar! Best of wishes for a gentle healing. I can only second all the reminders to be careful.

I came off my bike just before Christmas, and sprained my wrist and got a couple of feisty bruises, and didn't realize until much later that I had hit the ground hard enough to put cracks in my helmet. And even that quite mild bump was enough that a week later, I tired easily and was happy to spend hours just staring into space. Heads are precious things. Good luck!
