I have several symptoms involving my abdomen, colon and bowel movements, I can have a few or several days of normal bowel movement, then every so often I will need to have a bowel movement and my abdomen feels that same pain when you have diarrhea, stools will sometimes come out formed and other times I might spend a long time on the toilet passing stool and a lot of it. the entire time I am having abdominal pain and 2 different times I threw up at the same time. I also have a lot of nausea. Sometimes when I have a bowel movement my colon or rectum stings on the inside for 5 or so minutes after the bowel movement.
