Stray Kids' Felix is facing some health difficulties.

On February 9, JYP Entertainment announced on the official fan community that Felix had recently felt discomfort in his lower back. After visiting the doctors, Felix was diagnosed with Lumbar Intervertebral Disc Herniation. The Lumbar Intervertebral Disc Herniation is an illness in which the disc protrudes and causes back pain and neurological symptoms. The symptoms include radiating pain and numbness in the legs, along with back pains.

According to JYP Entertainment, "Felix has no issues with his daily life. However, he will refrain from postures and actions that put a strain on his back as much as possible." Therefore, Felix will be refraining from doing any complex choreographies or dance moves. 

JYP Entertainment revealed that Felix will be concentrating on his treatment and will be sitting out from some performances at the fan meeting 'Love Stray- Skids' Chocolate Factory' that will be held from the 12th to the 13th for a speedy recovery.

The agency added, "We apologize for causing concern to Stay (fandom name) who must have been waiting for Felix's performance."
