Due to privacy laws, doctors couldn’t reveal when the Poison frontman left the hospital and where he’ll be receiving further treatment, but did acknowledge that he is “a very lucky person” and “improving.” “I really expect that he will fortunately make a 100 percent recovery,” said Dr. Joseph Zabramski, during a press conference today at the Barrow Neurological Institute at St. Joseph’s Hospital. “He’s just one of those lucky people – 10 to 20 percent who make a complete recovery and can resume all of their normal activities.”
