Pussycat Dolls alum Jessica Sutta has revealed she sustained a debilitating injury after getting a COVID-19 vaccine.

The singer shared that she began experiencing troubling symptoms just days after receiving her second dose of the Moderna vaccine in 2021.

"I woke up with a muscle spasm in my right rib that just would not get out," she recalled during an interview with Daily Mail.

"It felt like a knife inside was burning, and it felt like I was on the brink of death."

Sutta, who then started experiencing spasms and tremors in her legs, said she feels her body has been "completely hijacked".

"Any physical activity I pay for the next day, and my body just flares, and it's very disappointing because I love to dance. It's who I am," she said.

Her symptoms also took a toll on her personal life and she had trouble caring for her three-year-old son.

"There's times where I can't lift him. I can't put him in the car, I need someone to help me," she said of her son, who was a newborn when her symptoms began.

"There's days that I can't get out of bed, and I'm on the heating pad, and there's so much mum guilt."

While doctors initially thought Sutta had multiple sclerosis, she finally got some answers seven months ago when she was diagnosed with vaccine-induced lupus.

"I'm not 'anti' anything," she said. "I'm just anti being sick."
