Per my other post on foods that cause pain I am not certain this discomfort, a stabbing pain in my colon, isn't something more serious. I am about 4 days away from my MD so I thought I would see if anyone here had any thoughts. If you type "sharp colon pain" into your browser almost all of the hits deal with colon cancer. Anything less deadly come to mind as a cause? I have had bowel problems in the past but nevermore than a mild ache. It almost seems to be radiating into my back. I have to be realistic about the worst case scenario but all I can think of is the cancer possibility. No blood, no diarrea, andI had a negative Barium Enema(air)test a month ago. Any thoughts?
