HaHa revealed just how much physical pains the members of Running Man have gone through in the last 7 years.
He revealed that shows such as Infinity Challenge and Running Man, caused many injuries. He even received surgery for his spinal disc injury.
My spinal disc injury became so bad that I needed to undergo a procedure. My 7th disc burst. But I couldnt say that I was not well. I thought everyone went through the same thing. It could be that my doctor was exaggerating, but he told me I was nearly paralyzed.
