Hi, I have had abdominal pain in my lower abdomen for the last 5.5 hours. The first 3 hours I had constant diarrhea. Now the pain is still the same but I am unable to go to the bathroom. The last time I went to the bathroom I thought I was having more diarrhea, but when I looked the toilet was just filled with bright red liquid blood- nothing else. Any idea what could be the issue?
