my girlfriend has had issues with sever pain in her lower abdominal area, hard strain to bowel movements and mucus and bleeding comes with it sometimes both or one or the other...shes seen a Gastroenterologist and done a colonoscopy her intestines are clear and colon is also. still has the pains and the same issues the doctor said he even did biopsies to test further issues and the tests were clear. My question is why is she still having these issues of pain and bowel issues? they ruled out ibs and other issues also from these tests
