2NE1's powerhouse singer Park Bom had a lot of fans worried after her lymph nodes appeared swollen during a recent performance.

On May 23, KBS aired a special episode of "Yoo Hee Yeol's Sketchbook," where musicians gathered to pay their condolences for the Sewol ferry tragedy. During this episode (which was filmed weeks in advance) 2NE1 performed the unplugged version of "Come Back Home" as well as hit single "Missing You."

After the episode aired, many viewers began pointing out what appeared to be Park Bom's swollen lymph nodes on the right side of her neck. It was also reported that CL lost her voice during the taping and was rushed to the emergency room.

On 2NE1TV, Park Bom had stated that she suffered from a lymphatic disease, which caused her lymph nodes to swell and also contributed to the swelling of her facial features.

Many Blackjacks (2NE1 fans) not only grew concerned seeing the alleged swollen lymph nodes, but also used this to criticize those who have bashed the 2NE1 singer for her alleged weight fluctuation and plastic surgery.

"And there it is people," tweeted BlackJackLover on Twitter on May 25. "To you saying Bom haven't got anything wrong with her lymph nodes. And she still sounds amazing".

"You would even see her on 2NE1TV putting ice on her cheeks and neck to keep the swelling down," wrote Firegirl on YouTube on May 25.  "So whenever I hear people talking about the 'constant surgery' she apparently gets, I wonder if they remember that she has this problem instead of blaming it on surgery."

Whether it is due to Park Bom's condition or otherwise, a lot of 2NE1 fans are showing their concern and care for the singer. Hopefully Park Bom is doing fine now.
