What are the symptoms of peritonitis?
When the appendix ruptures, the patient may suddenly feel better. But soon after, the entire abdomen may become distended with gas and fluid and will likely feel tight, hard and tender to the touch. He may also have pain throughout the abdomen, but may not have the severe, localized pain of appendicitis. In addition, he may not be able to pass gas or have a bowel movement because of the inflammation. Other signs and symptoms may include a fever, thirst and a low urine output.
