Knees Give Me A Break Please!!!

This post might not be as funny as some of the rest. I'm VERY frustrated. I woke up Saturday morning and went and walked a 5k. My knees felt a little stiff afterward, but no big deal. I went to the gym Saturday night and did 10 minutes of treadmill sprints, but my knees were hurting pretty bad so I gave it up. A couple of sharp pains, but mostly just extreme tightness. I skipped the gym Sunday. Monday I went to my chiropractor who thinks I've twisted both knees. He adjusted them and told me to take another night off. Today was supposed to be a workout with my trainer, but he is sick. I went to the gym and did upper body and arms, finishing up with 20 minutes on level one on the eliptical. My knees didn't hurt at all while I was on there. Now they are SCREAMING. I have ice on them again. They hurt on the inside of my leg just below the knee cap. Maybe this isn't even my knees. It's odd that they both hurt in the same place. I can't afford an injury. I'm just getting started. EEEEERRRRR!!!!
