Ouch -- good show there!  Best thing to do in general is keep that sucker good and clean.  And don't walk into any more rakes.
I put myself into physical therapy over the chickens.  Spent all summer 2010 digging post holes by hand for their run, which started me down the path to tendonitis/tendon impingement in my right shoulder.  THEN, to top it off, one soggy morning I slipped in the run, grabbed the house for support, and wrenched the daylights out of the same shoulder.  Spent two weeks holding it folded up against my chest because it hurt so bad, then we to PT.   Sounds like it's going to be with me for life, too, since it's started clicking and pulling again with the weather getting cooler.
Then this summer, when moving concrete half-blocks for the new brooder house, I dropped one on my foot.  While wearing canvas shoes.  Much swearing and rolling on the ground ensued.  Foot turned a pleasant shade of greeny purple.
Oh, yeah, and summer 2010 I also crushed the end of my thumb with a hammer while putting together braces for those posts I was setting.  Set two posts immediately afterwards, too, didn't have much choice.  Brother-in-law (an athletic trainer) claims I probably broke it, but it wasn't displaced, so nobody was going to do anything for me.
I guess the moral of the story is that people like you and I should probably spend our entire lives in a padded room somewhere 
   But the good news is that we can be klutz-buddies.
