Pain. Abdominal pain, usually in the left lower corner is the most common symptom. This can be accompanied by low back pain, fevers, chills sweats, nausea, and vomiting.
Like appendicitis. Begins with pain most commonly in the left lower quadrant of the abdomen. The pain is often recurrent rather than constant, and is often associated with fever, nausea, vomiting, changes in bowel movement frequent and consistency of stools, and symptoms suggesting urinary tract involvement may also occur. Gross blood in stool is uncommon, but trace blood often detected when tested. May perforate.
