Paranoia

My knee hurts but I ran anyway. 5 miles progression. Average of about 6:40. It hurt pretty bad the whole time I was running. As soon as I got done showering, I walked to my Bike and it felt almost to the point that it didn't hurt. After a half hour of sitting @ my desk it's tight again. I don't know if I should keep running on it but I'm going to because I don't know what else to do. Either I stop running on it until it stops hurting which will drive me nuts or I run on it until it hurts to much to run on it and stop running... or I keep running on it and the pain goes away. This whole thing has total put me in paranoia mode. I was having a pain @ my belt line and was worried about a hernia and today my chest hurts right above my heart and then my mind goes in to a whirlwind about my heart having problems. I guess the sky is falling too.
