K-pop boy band Stray Kids member Felix has been diagnosed with intervertebral disk herniation or herniated disk.
“We would like to provide information regarding Stray Kids' Felix's upcoming schedules. Felix recently visited a hospital after experiencing pain in his back. After a detailed examination. he was diagnosed with intervertebral disk herniation,” according to JYP Entertainment, Stray Kids’ agency on Feb. 9.

According to the Mayo Clinic website, “A herniated disk refers to a problem with one of the rubbery cushions (disks) that sit between the bones (vertebrae) that stack to make your spine.”
“A spinal disk has a soft, jellylike center (nucleus) encased in a tougher, rubbery exterior (annulus). Sometimes called a slipped disk or a ruptured disk, a herniated disk occurs when some of the nucleus pushes out through a tear in the annulus. A herniated disk, which can occur in any part of the spine, most often occurs in the lower back. Depending on where the herniated disk is, it can result in pain, numbness, or weakness in an arm or leg,” it added.
It explained that “many people have no symptoms from a herniated disk. For people who do have symptoms, the symptoms tend to improve over time. Surgery is usually not necessary to relieve the problem.”
JYP Entertainment is getting treated for the herniated disk and doctors advised that he should avoid activities that will put pressure to his waist.
“While there is no effect on his everyday activities, as doctors have recommended that he avoid postures and activities that pressure his waist Felix will be avoiding any strenuous activities while receiving treatment for prompt recovery,” it said.
As a result, the agency added, Felix’s performance in certain parts of the upcoming fan meeting “Stray Kids 2ND #LoveSTAY SKZ'S Chocolate Factory” slated on Feb. 12 and 13 may be limited.
“Felix will be participating in stage performances after doctors confirm that his back has fully recovered. JYPE will provide our utmost to support the artist's recovery. We apologize for having to share the sudden news and causing concern to all STAY who have been looking forward to seeing Felix perform,” it said.
