Marianne Keith, 52, went to the hospital with severe abdominal pain earlier this year, and her physician recommended she have a transvaginal ultrasound.
What ensued, Keith says, was nothing she could've predicted - an hour of brutal physical abuse that left her with internal injuries and recurring nightmares.
"It felt like I was being raped," she said in an interview.
"Like somebody was intentionally hurting me."
Keith has therefore sued the Advocate Condell Medical Center in Libertyville, Ill., where she underwent the procedure, for medical battery.
She claims in the lawsuit that the technician "repeatedly jammed the probe in to various internal portions of [her] vagina, including her cervix," for an hour.
