Yes: Yes your doctor, have the issue evaluated. This evaluation may include a pelvic exam and imaging studies such as a ct scan.

Exam is appropriate: You have localized your problem to the pelvis. The problem may be GI related (e.g. Colonic/ rectal inflammation, mass, rectal/anal dysfunction, colonic dysmotility), but may be extrinsic to the GI tract (bladder, peri-uterine, vaginal). Exam is definitely warranted for diagnosis ; appropriate treatment.
