Francis will not be participating in three events in the coming days “due to a recurrence of sciatica,” according to a statement from Vatican spokesman Matteo Bruni on Saturday.

The 84-year-old pope will go ahead with the Angelus blessing on Saturday, delivered from the Apostolic Library instead of a window overlooking St. Peter’s Square due to the virus resurgence. But he won’t say Mass in the Vatican Basilica on Sunday or planned evening prayer at St. Paul’s Basilica to close out a week of prayer, and a meeting with the diplomatic corps to the Holy See set for Monday will be rescheduled, said the Vatican.

Nerve pain also previously forced the pope to skip New Year’s ceremonies in St. Peter’s Basilica.

The flareup of Francis’ sciatica raises questions about his planned March 3-8 trip to Iraq, a visit that some have questioned by many given the coronavirus pandemic.

Papal trips are grueling under any circumstance, with many appointments each day, long Masses and reception lines, and multiple transfers via car and plane.

Pope Francis has spoken openly about his sciatica in the past. It is a form of pain in the lower body caused by compression or irritation on nerve roots or on the sciatic nerve, which runs from the lower spine down the thigh.
