Brazil ex-president Bolsonaro again has procedure

Former Brazilian President Jair Bolsonaro, who was temporarily released from prison last week for hernia treatment, underwent an unscheduled procedure on Tuesday to treat persistent hiccups, according to his doctors.
Bolsonaro, 70, had already undergone two surgical procedures at a Brasilia hospital for the same reason since Saturday, as well as hernia surgery.
The ex-president underwent supplementary “phrenic nerve block procedure” after ⁠presenting new episodes of hiccups, according to a medical note released late on Tuesday.
In medical literature, the phrenic nerve is described as a vital nerve originating in the neck that controls the diaphragm, the primary muscle for breathing.
Bolsonaro will undergo a digestive endoscopy on Wednesday to assess gastroesphageal reflux.
