He was rushed to the hospital and underwent five hours of surgery.
He suffered three fractures to his shoulder, broken fingers and elbow injuries as well as facial, eye and back injuries when he fell heavily.
Writing on U2.com Bono stated :
“The consequences of this freak accident are significant enough that I will have to concentrate hard to be ready for the U2 tour in fitness terms… as a result I have canceled every public appearance and decided this missive is all the communication I can manage for the first half of 2015, beyond muttering and singing to myself of course,” he wrote.
"I broke my hand, my shoulder, my elbow and my face but the real injury this year was to my Irish pride as it was discovered that under my tracksuit I was wearing yellow and black Lycra cycling shorts,'' he said.
"Yes, LYCRA. This is not very rock 'n' roll. Recovery has been more difficult than I thought.
"As I write this, it is not clear that I will ever play guitar again. The band have reminded me that neither they nor Western civilization are depending on this.
"I personally would very much miss fingering the frets of my green Irish falcon or my (RED) Gretsch. Just for the pleasure, aside from writing tunes.
"But then does the Edge, or Jimmy Page, or any guitarist you know have a titanium elbow, as I do now? I'm all elbows, I am."
He revealed he is taking major painkillers to numb the pain from his injuries.
“These Percocets (painkillers) are pretty perky until they are not...you are in a kind of fluffy land floating till you wake the next morning with a bump,” he said.
Bono wrote he will have to “concentrate hard” to be fit to perform on stage for the upcoming tour.
