Done with days: Fishy breakfast, busted body

I slept in my own bed in my own house for the first time in two weeks last night. Felt great.
What did not feel great was coming home from CrossFit this morning and realizing that I also hadn't been grocery shopping in two weeks. I'm going to take care of that after work today. But that was no help this morning when the only paleo food I could scrounge up was a warm can of Whole Foods tuna and a plum.
I don't know if it was "Elizabeth" or the breakfast that made me want to puke more.
On another note: I've been nursing a couple injuries for about a month now. The first happened when I fucked up a hang clean. The second is a knee injury. I didn't really know the cause of that one until Saturday night when I asked my brother to take a look.
Some background: My brother is the head athletic trainer at a local college and has been on staff for several college and professional athletic teams. So he knows what he's talking about.
I asked him to take a look at my wrist and explained how I thought I injured it. Turns out, my injury isn't in my wrist at all. Apparently I strained some really small muscles in my forearm while incorrectly trying to heft up a lot of weight with them. That caused caused the tendons to swell. It was most painful in the wrist because the tendons run through a smallish tunnel on the way to my hand. When they're swollen, they've got a lot less space to run through, which amplifies the pain. (If I've got terminology for tendons and muscles wrong, forgive me. You get the gist.)
Anyway, in the process of rehabbing that injury, my brother asked to see some of the other movements we are doing in CrossFit. Generally, he's stoked on the work outs, loves Olympic lifting and the other basic exercises we do. He does have some concerns about the body's natural tendency to sacrifice form for speed in a competitive atmosphere.
And his example of that was my squatting. He could immediately tell I my left knee is injured because I was favoring my right one every time I squatted. And he said that injury likely occurred because I was squatting incorrectly in the first place.
That's no surprise to me. Every time I squat heavy weight, my knees tend to buckle in. My trainers have pointed that out and told me to stop it, but I guess I never understood the consequences of not being extra careful while following that advice. In addition, I guess the alignment of my knees (and being a woman with wide-ish hips) make me predisposed to this sort of problem. The solution is to be extra conscious of pushing out my knees (ie, pointing in the same direction as my feet) when I swat and narrowing my stance.
So usually I wouldn't write about my aches and pains -- I'm not a pansy or anything. But I guess I just realized that we have to take a higher level of personal responsibility doing these intense workouts. If something hurts, it's important to ask for help figuring out what might be the cause. The trainers at CrossFit are awesome and really knowledgeable, but they can't be everywhere and see everything all the time.
I'm really looking forward to building momentum at the box this week. How's everyone else doing on Paleo?
