"Thanks to everybody that came to @hydebellagio last night for the show and sound check," Barker captioned an Instagram post. "I had a 104 temp and was severely nauseous and dizzy. The paramedics demanded I not play and go to the hospital asap. I said I'm playing till I either pass out, throw up or die. Met so many of you guys at sound check that came from Mexico, Australia etc. and there was no way I was gonna let you guys down. I got thru my entire set and I appreciate all the love."
