Every few weeks since my early 40s, I wake up with a knee injury. I was fine when I went to bed, now I'm limping to the bathroom for Advil. I can see a little swelling on the top of my knee. It feels warm too.
I think sort of evil little being must have bonked me in the night?
All I did was sleep!
This morning, it happened. Thankfully I could walk to work and back, a slow 1/2 mile to get things moving again, but that doesn't always help.
Might not be age though, could be water of the knee says my dad. I guess I'll have to have it checked out.
