What Is The Treatment For Severe Pelvic Pain?

Hi, I am a 58 yr. old post-menopausal woman with pelvic pain. Normal Pap test, just had D & C for endometrial hyperplasia -- normal pathology report. Having tremendous pain with leg adduction, getting out of and into my car, turning in bed, getting up from my sofa, and pain when walking a lot (am an RN who works 12 hr. shifts). Does this sound like pelvic girdle pain, and if so, is chiropractic/physiotherapy the best approach to treatment? Thanks!
