Understanding New and Severe Abdominal Pain

Your symptoms are most consistent with "colitis," an infection or inflammation of the colon.

One common cause of colitis is an infection that can develop following antibiotic treatment. Infections from contaminated food, such as salmonella, shigella, or campylobacter can cause similar symptoms.

It is also possible for an autoimmune condition to result in colitis. Autoimmune problems that cause colitis include Crohn's disease and ulcerative colitis.
