Anthony Kiedis is back on the road after suffering an intestinal flu last summer, but despite the health scare, the Red Hot Chili Peppers frontman is still going full-force onstage.

“I’m always getting banged up, and hurt, and repairing, and recovering, and hurting, and it’s just normal,” the rocker tells ET Canada at the band’s concert in Toronto. “At the moment, I have a torn tendon in my ankle from spinning around night after night, but it’ll heal.”

Although he remains unfazed by his frequent injuries, the 54-year-old admits he still gets nervous before performances, even after over 30 years in music.

“I’d be a little bit lost without the nerves,” he says. “I’d want to be borderline ready to throw up from nerves, and then I’m ready to go.”

It turns out those butterflies have skipped a generation, as Kiedis’ 9-year-old son Everly has been joining his famous father onstage throughout the band’s current world tour. The rock star insists it’s at his son’s behest, though, joking, “I’m not trying to be the stage mom pushing him into this thing!”
