Axl Rose didn’t go “numb when he learned to see” recently, as Guns N’ Roses‘ “Civil War” lyrics say, but instead, he went numb thanks to his battle with TMJ, the rocker revealed during the band’s sprawling three-hour show at New Jersey’s MetLife Stadium on Wednesday (Aug. 12).

Rose shared his experience and injected it with humor between introducing the band members — Slash, Duff McKagen, Dizzy Reed, Richard Fortus and Isaac Carpenter — joking that he currently had Bugs Bunny in his ear boppin’ around, and that he had some dental work just days ago to deal with the condition. (According to the Mayo Clinic, TMJ involves the temporomandibular joint causing pain as the jaw moves around, and can also cause popping sounds in the jaw.)
