Adele has candidly shared more details about the extent of her back problems during a recent performance at her ‘Weekends With Adele’ residency in Las Vegas. The 34-year-old songstress expressed that she was performing with a disintegrated disk in her spine, saying: “Is anyone else kind of my age starting getting bad knees? I have got really bad sciatica in my left leg and my L5 disc is not fucking there anymore. It’s worn away.”According to the Cleveland Clinic, the L5 disk’s associated nerve, situated at the lower back, is responsible for providing “sensation to the outer side of your lower leg, the upper part of your foot and the space between your first and second toe”.
