Many tests: It sounds like u have functional defecation disorder, or FDD. As it is disorder of function, ur best test is anorectal manometry: a pressure-sensing catheter is placed in the rectum & records pressures while you try to evacuate stool. GI doctors have equipment for this. Alternative tests are 1) defecating proctogram, which involves X-rays and Barium enema, or 2) MRI defecography in Radiology Dept.
