Pope Francis appeared at his weekly general audience on Wednesday, a day after he went to the hospital for a checkup.

The Vatican provided no details about the medical tests Francis underwent on Tuesday at Rome’s Gemelli hospital. Francis, 86, appeared in good form, though, at his audience in St. Peter’s Square, zipping around the square in his popemobile greeting the faithful. He also had two meetings Wednesday morning beforehand, the Vatican said.

Francis spent three days at the Gemelli Hospital in late March. Initially, the Vatican said he had gone in for scheduled tests, but the pontiff later revealed he had felt pain in his chest and was rushed to the hospital where bronchitis was diagnosed. He was put on intravenous antibiotics and was released April 1, quipping that he was “still alive.”

The Argentine pope had part of one lung removed when he was a young man. He also suffers from sciatica nerve pain and has been using a wheelchair and walker for more than a year because of strained ligaments in his knee.

Francis has had a packed schedule of late, with multiple audiences each day. The Vatican has recently confirmed a travel-filled August, when the Holy See and Italy are usually on vacation, with a four-day visit to Portugal the first week of August and a similarly long trip to Mongolia starting Aug. 31.

In a sign that the trips were very much on, the Vatican on Tuesday released the planned itinerary for Francis’ visit to Portugal for World Youth Day events from Aug. 2-6. The itinerary confirms a typically busy schedule that includes all the protocol meetings of an official state visit plus multiple events with young people and a day trip to the Marian shrine at Fatima.
