I awoke sometime after midnight to a severely throbbing knee. Chris was still awake, so he took a look and found that my right knee was swollen. There was also a small bruise that I don't remember getting. I took two pain killers which didn't help. Chris put an ice pack on it and after a few hours the pain was gone.
This morning I had a little stiffness in the joint and there's still a small amount of swelling. Chris called my APN to report the incident and see what we should do. I didn't feel like it was an emergency room situation, but it was a strange enough occurrence that we both thought we should report it. My regular APN was out, but the nurse subbing for her offered to have a look at it if we wanted to come in. Since it no longer hurt I elected to sit tight.
I honestly don't remember bumping into anything, but the bruise had to come from somewhere. We'll keep an eye on it, but I'm hoping it doesn't merit anything more than a footnote.
