ouch!

Have you ever felt like your rib cage was squishing your lungs so hard you can't breath? I have only felt this twice in my life. A couple years ago when I got Bronchitis, and last night. I can't say exactly what caused it last night, and as sure as I was last night that it wasn't from running, I actually think I have changed my mind! I honestly think I ran way to hard, and way to fast for my level. I am not going to do that again! :)
