In general, diagnosing appendicitis on your own, especially for people without medical knowledge, is not very reliable. Appendicitis is an inflammatory disease of the appendix caused by a variety of factors and is a relatively common clinical condition. Typical clinical manifestations of appendicitis are metastatic right lower abdominal pain, combined with gastrointestinal symptoms such as nausea and vomiting, as well as systemic symptoms such as fever and malaise. Clinical diagnosis is relatively simple, but self-diagnosis is still possible misdiagnosis. Appendicitis should be distinguished from perforated peptic ulcers, right-sided ureteral stones, certain gynecological diseases (such as ectopic pregnancy, acute salpingitis, acute pelvic inflammatory disease, etc.) acute mesenteric lymphadenitis. In addition to symptoms, the diagnosis of appendicitis depends on physical examination, supplemented by laboratory tests (e.g., routine blood tests), imaging tests (e.g., abdominal plain films, ultrasound, etc.). When you suspect that you have appendicitis, it is recommended that you go to the hospital in time to get a clear diagnosis and follow the doctor’s instructions for treatment as soon as possible.
