Kim Kardashian's little sister has opened up in the latest episode of family reality series Keeping Up With the Kardashians, revealing she wakes up in the middle of the night and cannot move.

In the show, which airs on Sunday (06Nov16), Kendall tells her mum Kris Jenner, "Everyone says I'm fine, but I don't feel fine."

Almost a year ago (Dec15), Jenner was hospitalised for exhaustion, explaining at the time, "It was definitely a wake-up call that I need to take better care of myself."

And earlier this month (Oct16) in an explosive Keeping Up With the Kardashians teaser, she took aim at her famous family members for not taking her health issues seriously.

"I'm done arguing with people because I don't feel fine," she raged. "I promise one day when I'm rushed to the hospital, then you guys are going to wake up."
