Former U.S. President Jimmy Carter is doing well – “up and walking” – a day after undergoing a brain surgery, his pastor says.

Reverend Tony Lowden of Maranatha Baptist Church on Wednesday paid a visit to Carter in an Atlanta hospital.

“His spirits are good and he is up and walking,” Lowden told reporters.

Carter Center spokeswoman Deanna Congileo has said there were no complications during Carter’s Tuesday surgery at Emory University Hospital for a subdural hematoma, blood trapped on the brain’s surface.

She said he would remain hospitalized under observation. It’s unclear when he’ll be released from the hospital.

According to the center, the bleeding was connected to Carter’s recent falls. A Spring fall required Carter to get hip replacement surgery. He fell twice in October, hitting his head at least once.

Lowden said he expects Carter to ask when can he resume teaching Sunday School. Carter, 95, has been teaching Sunday School regularly at Maranatha Baptist for decades.

“I am going to tell him that we have everything in order at the church and he doesn’t have to worry about anything,” Lowden said. “There is no need to rush.”
