Appendicitis is generally divided into chronic and acute appendicitis. Both chronic and acute appendicitis can cause pain, which is usually severe. In cases of acute appendicitis, if the pain subsides after a while, it is actually more dangerous. It may indicate complications such as intestinal perforation or intestinal necrosis, leading to gradually diminishing pain. In such cases, timely surgical removal is necessary; otherwise, if local ulceration occurs, it can potentially affect the entire intestine. Thus, appendicitis generally causes pain, especially during the chronic phase. The pain is quite noticeable and, although generally bearable, can directly impact the quality of life.
