Let me ask you that in the last few days, I often have abdominal pain, about 5 minutes, it goes away, especially if I go outside, the pain will quickly decrease. My bowel movements are not moldy, usually loose and small. Usually when I eat, it hurts. Especially when I drink milk, my stomach hurts. So the doctor asked me, what is the symptom of abdominal pain, defecation after eating?
