Balancing act

National Senior Games is two weeks away, and I'm having to learn to balance training with trying to be strong, injury-free, and as pain-free as possible.
My right elbow has been sore since I jammed it on a sliding pole box at practice a couple weeks ago. My right shoulder is always a little sore, just from vaulting, and my left knee has been bothering me for a few weeks now -- just "routine" soreness, I think, and nothing serious.
So ... I don't want to lay off completely, but I don't want to do any more damage before Nationals. I want to feel as good as I can when the time comes.
This morning, I did my core-strengthening low-bar exercises, then I set up my new low hurdles in the side yard, and did some sprint drills through those with a medicine ball and a pole. 
I've iced my knee twice today, and I'll do it again here in a little while. It feels pretty good, really, so I don't think there's anything going on inside there, except maybe some inflammation and maybe a little swelling. There's no visible swelling, but completely bending the leg at the knee is not comfortable.
