Unfortunately, since I cannot examine patients on this forum, I really cannot offer patients a specific diagnosis. If your doctor actually observed an anal fissure, then this can be treated with increased fiber in the diet and stool softeners. If the fissue fails to heal with this conservative approach, then there are other medical and surgical remedies that can be used.
Unfortunately, IBS is a so-called "wastebasket diagnosis," which basically means that doctors cannot find another explanation for the abdominal cramps and diarrhea or/and constipation that are typically associated with IBS.
