It is not always painful for patients with gastroenteritis, because each person’s constitution, dietary factors, personal habits, irritation factors, or other environmental factors vary, and there is a great deal of individual variability, so some patients may have stomach pain, some may only have vague pain, and some may have severe pain. Therefore, there is no way to determine whether it is gastroenteritis or not simply by the pain in the stomach, nor can we infer that the stomach must be painful or not just because it is gastroenteritis. Therefore, it is necessary to combine relevant auxiliary examinations with targeted medications for comprehensive treatment. You must be guided by the attending physician, combined with stool routine, blood routine, electrolytes, abdominal fluoroscopy, ultrasound and other related tests, comprehensive analysis and judgment of the condition, and then carry out targeted treatment.
