Thanks for your query and an elucidated history. The most clinching history is you have diarrhea and lower back pain. Since you have undergone all other tests and an opinion of a Gynecologist, which have turned out to be normal, I would advise you the following:Get blood and urine and stool tested. Ultrasonography of the whole abdomen course of an antibiotic, metronidazole and probiotic along with anti-spasmodic whenever necessary. This should solve your problem. If required take an opinion of a Gastroenterologist and get colonoscopy and CT scan of the abdomen done, considering your pre-menopausal age to rule out any cancers. . </s>
