These were some bad vibrations.

An Arizona woman needed surgery to remove a sex toy that somehow got stuck in her bladder — while still vibrating, according to a report.

The unidentified woman from Mesa told Arizona Family that she tried out her new Vesper Vibrator Necklace in the bedroom with her boyfriend earlier this month, only using it outside her body as intended.

“I moved and out of nowhere I just felt a really sharp pain,” she said, suddenly losing the pencil-thin stainless steel vibrator that can also be worn as a necklace.

“First reaction was panic because I had just lost something inside of me that was still going off,” she said, confirming it was “still vibrating.”

“Every time it went off it was like my entire abdomen was vibrating,” she told Arizona Family.

She went to the ER, but pelvic exams failed to find it, the report says.

“The emergency room staff wasn’t able to find it in the vagina,” said OBGYN Greg Marchand, who finally conducted an X-ray.

“I was really surprised when I’m looking in the abdomen and realizing this device is actually in the bladder,” Marchand said, with the sex toy lodged sideways after entering the bladder via her urethra.

“I’ve never seen a case like this in my entire career.”

The vibrator was eventually removed safely through surgery, ending her bad vibrations.

She plans to file a lawsuit against Crave, the company that makes the Vesper Vibrator Necklace — and admitted she is “probably” done with using sex toys.

The company has worked with “Real Housewives” star Carole Radziwill in creating her own $69 version.

A spokeswoman for the company told The Post that “the Vesper cannot enter an individual’s urethra by itself” and comes with a “clear safety label” warning against insertion.

“The Vesper is designed for external use only and we stand behind its safety and quality for this use,” the spokeswoman said.

“Because the woman has not contacted us, we have no direct insights into how the product was actually used.”

Crave remains committed to its mission of “bringing modern design and safe products to a category historically dominated by novelty items,” the spokeswoman said.
