Patients with enteritis mostly experience symptoms of abdominal pain, mostly manifesting as mild to moderate abdominal pain. Spasmodic pain in the lower left abdomen or lower abdomen is more common, and sometimes it can involve the entire abdomen. Some patients also have these symptoms where urgency and severe straining follow a bowel movement, and abdominal pain relieves after defecation. In cases with milder conditions, the pain is only a discomfort in the abdomen or mild obscure pain. Moderate cases may have mild tenderness in the lower left abdomen, and sometimes doctors can also feel a spasming colon. In severe cases, such as those complicated by toxic megacolon or when inflammation spreads to the peritoneum, there can be persistent severe abdominal pain.
