Diagnosis will require and exam, perhaps further testing.
Pelvic exam, maybe an MRI...ultrasound is worthless for ligment, bone and nerve, for the most part.
Pelvic pain can be from many different problems.
endometriosis...would come more with the period.
Ovarian problems, most would show up on ultrasound.
Uterine fibroids, same.
Pelvic pain syndrome, nerve pain...needs physical therapy
Bowel problem, mainly with the colon.
Chronic bladder problems.
OK, so that is an initial answer….
