I have a fractured finger!

Did you know you could break a finger while you sleep? I didn't either, until Thursday morning when I pulled the sheets back to get out of bed - and yelped with pain! The middle finger on my left hand felt like someone had driven a hot nail into it. As I had an appointment with my massage therapist at 11.30, I asked her if she could see what it is. I thought it may be referred pain from my neck and shoulder, but she worked on trigger points in my shoulder and neck for 20 minutes, then she shook her head and said there is no referred pain from the neck. She advised me to put an ice pack on it, and splint the sore finger between icypole sticks (of which I have none).
So I went to our chemist, who looked at my finger and said she could see bruising. She said it may be fractured, and produced a proper little finger splint to sell me. Isn't this nifty??
