All in all I had an excellent birthday. I had a great time at my party, I got some excellent gifts, and I ate lots of cake. Thanks to everyone who was able to make it. Hooray!
One birthday present I could really do without, though, was whatever I did to my tailbone during practice. Afterwards it hurt to sit at all, and I spent the night alternating between resting on each hip. When I woke up today I could barely move. I'm definitely seeing the doctor when I can, because I think I really hurt myself.
While I've heard that ice is good for tailbone injuries, I'm going to see if eating large quantities of birthday cake helps.
