This study evaluated the level of pelvic pain experienced during outpatient diagnostic hysteroscopy. 246 patients underwent office hysteroscopy using a 4mm traditional optic hysteroscope. Pain was rated on a visual analogue scale from 0-10. The mean pain score was 4.5. There was no significant difference in pain levels between pre-menopausal and post-menopausal women or between multiparous and nulliparous women, except nulliparous women experienced more pain. In conclusion, the pain during office hysteroscopy was generally mild to moderate.
