4 miles last night

Went out and ran a little over 4 miles last night with the guys. My IT band didn't bother me at all so that is good. My left "hip" or whatever that is did however and it keeps getting progressively worse. Coach thinks that might be my left IT band because that runs from your hip joint all the way to your knee. Today the back of my hip bone hurts too. Who knows what the heck is wrong with me.
