moderately active

I've done something foolish to my right arm. I'm pretty sure it has to do with weight lifting, because pain of this kind usually does.
I was in a car accident years ago, and as a souvenir of the experience, I got a plate and six pins in the bone of my upper right arm. It would, I have been told, be dangerous to remove at this point, given nerve proximity and other such concerns, so its here to stay.
But sometimes it acts up. Generally it is because I have tried to lift something that the plate thinks is too heavy for it, and given the inflexibility of the plate and pins, the pain in the bone is fairly long-lasting. It becomes painful to attempt to touch my own face, reach to the right or left, raise my hand straight up or hold pretty much anything in my hand for very long. It is, in short, seriously sucky.
It doesn't mean I can't run, but it does mean I don't really want to. After a while, a couple of days of painful movement, I get sort of scared of it, and end up spending decent periods of time trying to stay as still as possible, waiting for it to be gone and done with. I was in that mode for much of the weekend, although yesterday, talking to a friend about how much it hurts and how much it sucks that it hurts, I remembered how much the rest of the stuff I broke during that accident had hurt. It helped a lot to remember that the arm was never the worst of it, I've lived through worse, months of it, with no real clear end in sight. So now I am up and moving and planning on going running early this afternoon. And then teaching a yoga class, which should be an interesting end to the day, and will also probably make me wish I still had that script for pain killers waiting for me at home.
