I am 19 Yr old female, and at age eleven my doctor told me that i had IBS, however he didnt un any tests or anything. he prescribed me zelnorm, witch i took for about a year but stopped taking it after no results were produced if anything it had increased my pain level. I now still experience all the symptoms that i first came to my doctor complaining of,such as extream abdominal pain after eating, with no exception to more healthy foods or unhealthy, unbearable pain during bowel movements and with the occurance of gas in the intestans. i am constantly either constipated or experiencing diarrhea there is not an in between. recently i have been experiencing an emence pain during sex, however the pain is not directly in the vagina but rather a result of pressure being put on my intestines. my doctor has run several blood test, urine tests, and performed a vaginal ultra sound and has found nothing. i belive that there is somthing wrong that may be far worse then IBS. Do you know what is wrong? Please help?
