What else can mimic appendicitis?

Other conditions that can mimic appendicitis include celiac disease Meckel’s diverticulitis, pelvic inflammatory disease (PID), inflammatory diseases of the right upper abdomen (gallbladder disease, liver disease, or perforated duodenal ulcer), right-sided diverticulitis, ectopic pregnancy, kidney diseases, and Crohn’s …

Can you still have appendicitis with normal blood work?

Acute appendicitis is a common surgical condition which can lead to severe complications. Recent work suggested that patients experiencing right lower abdominal pain, with normal white cell count (WCC) and C-reactive protein (CRP) are unlikely to have acute appendicitis and can be discharged.

How do I know if I have appendicitis or constipation?
