I having this problem just this march 11,2012.I went to an event last march 10 2011 and that night I was really holding my pee because of no restroom available,then in the next morning I did hold it again because of I'm lazy to get up from sleep,then suddenly I feel it will going out of me like I can't control it,so when I release it it feel my organ is painful and my tummy after a minutes I pee a little bit then I saw a little blood on the toilet paper.I was so scared so I keep checking it up if theres still blood,and it still some it's only little and not really red but still why I have it?....
