On the February 9 broadcast of MBC's 'I Live Alone', the Rainbow Association members revealed that Park Na Rae was not able to attend the recording session after undergoing vocal cord polyps surgery. 

Then, at the end of the broadcast, a preview for next week's episode showed Park Na Rae in the hospital, still recovering from her surgery. Because she was not able to use her voice to speak, she was seen relying on her iPad to vocalize her commands for her using AI. When the day of her discharge came, the nurse strongly advised that Park Na Rae refrain from hot and spicy foods. 

After seeing Park Na Rae's state in the preview, fans began expressing their concerns over the comedian's health. In response, Park Na Rae assured via SNS, "I'm doing okay! Just going through a repair stage so I can run like usual. I'm out of the hospital and have evolved into a nightingale." 

On February 10, Park Na Rae's agency JDB Entertainment also issued a statement of assurance, confirming, "Park Na Rae is recovering well after her vocal cord surgery. Next week, she will be back in the studio recording 'I Live Alone'." 

Meanwhile, during an appearance on the variety program 'Dr. Oh's Golden Clinic' last year, Park Na Rae opened up about her struggle with vocal cord polyps. "I've had two surgeries. But my vocal cords are still not well. I get steroid injections when it gets bad. I have another polyp currently," she explained.
