It was reported that Jung Yonghwa having just completed filming for We Got Married with Seohyun on the 24th, complained of dizziness and subsequently collapsed due to fatigue. He was immediately taken to hospital for treatment.
According to a FNC representative on the 25th, Jung Yonghwa was diagnosed to have developed [worsened] vocal cord polyps and acute laryngitis yesterday upon admittance for treatment. Although he can cure his acute laryngitis with medication, he would have to undergo surgery for his vocal cord polyps condition to restore his normal voice. But it was noted that nothing has been decided yet, and a decision would be taken after more scans and futher observation.
With no confirmed discharge date, CNBlue’s recording for Yoo Hee Yeol’s Sketchbook on the 25th will now have to be canceled. Schedules scheduled for the rest of the week will be decided, depending on Yonghwa’s speed of recovery.
Last April, Yonghwa during a broadcast experienced a cold and neck pains and was rushed to the hospital and diagnosed with vocal cord nodules.
Vocal cord nodules are small growths on the vocal cords that occur due to high levels of stress on the vocal cords (similar to a callus on the hand).
Since it was found at a very early stage, it was thought that it would be easily treated with some rest and relaxation.
Meanwhile, CNBlue had their comeback last May 19 with their second mini album "Blue Love" which is receiving a lot of love from fans.
