Knee Pain, Oh how I loathe thee

It's Wednesday, which is usually a training day for me. However....that lovely little friend of the runner, my knee, has been aching since Saturday's 5K. It's not bad, not constant, but hurts on top of my knee cap when I'm walking or after I've been sitting with my legs crossed for a while. I went out for a good run on Monday. My knee had been acting up a little since the race so I decided to run on the local clay track. I had no problems during the run, as a matter of fact the run seemed to help the pain. But now, after working 2 - 10hr shifts on my feet the pain is back. I decided to take the safe route and rest today rather than run. It has been a painful decision. How is it that in just a few short months and weeks I've become so addicted to this activity?? At work today, instead of focusing on the fact that I had allergies, or that I only got 2 hours of sleep last night (don't ask), I was devastated and completely distracted by the thought of having to skip my run tonight.

My Brain:
"Gosh, my knee is still aching"
"Eh...it's not that bad, get out there and tough it out kid"
"But what if it worsens?"
"Rub some dirt on it, suck it up! Pansy"
"No, it's really hurting"
"Is it really?"
"Yeah, there it is again"
"Maybe just a jog?"
"Elliptical?"
"Lazy arse"
"Ugh, I hate driving by the track instead of to it"
"Aww...my running clothes all laid out....sad"
"I'm officially depressed"

*sigh* even my post is depressing.  

Must...find...chocolate.......now!
