Pope Francis has been forced to cancel a trip to Florence this Sunday and Ash Wednesday services next week, because of an acute flare up of pain in his knee, the Vatican said on Friday.
The 84-year-old pope suffers from sciatica, a nerve condition that causes pain in his legs. He has recently read a few speeches sitting down, citing pain in his knee.
