Former Brazilian President Jair Bolsonaro underwent a nerve block procedure to address persistent hiccups following hernia surgery. Doctors blocked the right phrenic nerve, controlling breathing, with plans for a second procedure. Bolsonaro, 70, was recently sentenced to 27 years for plotting a coup. He received court authorization to leave prison for the surgery and used the hospital stay to endorse his son's 2026 presidential bid. His health issues stem from a 2018 stabbing.
