Painful disappointment

I did a PFT today...only to have to stop my 3-mile run halfway. The injury or whatever it is started hurting...and now I'm paying for it. I did increase my pull-ups to 10...and maintained my crunches at 100. Unfortunately, my running training is hurting...figuratively and literally.

I've made a doctor's appointment with one who does a lot of marathoning, so I figure he's familiar with most running injuries...
