question: At roller derby practice tonight we worked on a hitting drill where I ended up taking a few hard hits to my abdomen. Later on during scrimmage practice I fell hard landing right on my abdomen. It hurt bad and took me a minute to get up and recover. After practice on my way to car I had bad pain, felt like I had to have a bowel movement. I was doubled over. I went back in to the bathroom and nothing happen. Since being home I have had a small amount of diarrhea twice. Each time when I wiped there was bright red blood on toilet paper and I noticed drops of blood in toilet. I am not in severe pain but it is uncomfortable. Should I be worried?
