Please help. I ate sashimi (raw fish) 11 days ago and by that evening began to experience a great deal of pain/discomfort in my upper and lower abdomen. The pain has come and gone since, but occurs at least a few times a day every day. Bowel movements coincide with intense abdominal cramping/pain. I was purging in an attempt to lose weight for several weeks prior to this occurring - have stopped since this began. Eating foods will sometimes calm the discomfort, but then often trigger a delayed pain/cramp episode. What can I do?
