I have severe pelvic pain , lower abdominal pain , no infection , CT scan revealed nothing any ideas? I am a 58 yr. old female who has had a complete hysterectomy. I recently had a myocardial perfusion scan and experienced similar pain during this test , the same type during my CT. I also felt like my ribcage was being crushed . I have had several health issues in the last 15 or so years , seen numerous doctors and still have few answers.
