The specific causes of pain above the navel are multiple, such as early acute appendicitis, upper gastrointestinal ulcer, gastrointestinal spasm, periumbilical infection and even abdominal distension and tumor, etc. The specific causes need to be decided by combining the patient’s medical history, detailed physical examination and relevant auxiliary examinations. Early appendicitis pain in the navel is caused by the nerve reflex, so the pain is first shown above the navel, after 6-8 hours, the pain gradually shifts to the right lower abdomen, so individual patients complaining of pain in the navel may not necessarily be upper abdominal pain, but the root or cause of the disease may occur in the right lower abdomen.
