Hi. Thanks for your query. Noted your history of feeling of something left in the anus even after passing stool. Hence re-visit the bathroom and you pass only a corm sized ball and this happens several times in a day. It is frustrating for you. The commonest causes of this are: Proctitis meaning inflammation of the rectum which gives the feeling of something still left inside the rectum even after passing stool. Some case of IBS meaning irritable bowel syndrome can cause similar problems. Hence I would advise you the following: Examination of the stool on three consecutive days. Tests of blood and urine. Ultrasonography of the whole abdomen, particularly for the genito-urinary system. Per-rectal examination and ano-proctoscopy followed by colonoscopy can give a proper diagnosis and a plan for treatment. Medical management with a course of an antibiotic, metronidazole, antispasmodic, and treatment of anxiety and or stress are very important factors.
