The Boyz' Sunwoo has been diagnosed with neuralgia and neuritis in the midst of a group comeback.

On November 24, IST Entertainment announced Sunwoo was complaining of neck and shoulder pain, and though the label sought to take Sunwoo to the hospital right away, he expressed his desire to perform with The Boyz on 'Music Bank'. After filming for the music show, Sunwoo visited the hospital, and he was officially diagnosed with neuralgia and neuritis of the neck and shoulder.

The Boyz member has been advised to minimize excessive movement by a doctor, but he's said to have a "strong determination" to promote with the group for their "Watch It" comeback. Because of this, he'll be continuing with his activities "without overexerting himself" as much as possible.

"This is IST Entertainment.

We are making an announcement regarding The Boyz member Sunwoo's health and future activities.

This morning (November 24), Sunwoo complained of neck and shoulder pain, so immediately after today's music show pre-filming, he went to the hospital. He was then diagnosed with neuralgia and neuritis of the neck and shoulder area, and he underwent treatment.

Based on the doctor's advice, he needs to temporarily minimize excessive movement. We discussed Sunwoo's future participation in performances, and as Sunwoo expressed strong determination to take part in album promotions, we chose to respect the artist's opinion. It was then decided he would continue activities as much as possible without overexerting himself.

He'll be joining upcoming scheduled activities and taking part in the scheduled fan signing event, and it has been decided that, as much as possible, he will try to avoid any setbacks to the schedule that was promised to fans.

We will consider our artist's health our top priority, and we plan to continue to have him undergo continuous treatment and to carefully check his condition so that his injury does not worsen.

Thank you."
