Bono, the frontman of the Irish rock group U2 who was injured in a cycling accident last year, says his recovery has not been easy and he may never play guitar again.

In a blog on the group’s website, the 54-year-old rocker described how he blanked out on impact during the cycling accident in New York’s Central Park, which he said he could not blame on anyone but himself.

“Recovery has been more difficult than I thought,” he said in the message written from his home in Dublin.

Bono, who included an X-ray of his elbow in the blog titled Little Book of a Big Year Bono’s A to Z of 2014, said he did not remember how he ended up in a New York hospital with the bone in his upper arm sticking through his leather jacket.

“Very punk rock as injuries go,” he added.

Bono’s arm was shattered in six places and doctors inserted three metal plates and 18 screws to repair the injury.

He required hours of surgery for fractures and has had extensive therapy, but he is expected to make a full recovery.

Bono also referred to revelations he made last year when he told a British talk show host that the reason he always wore his trademark sunglass was that he had suffered from the eye disease glaucoma for two decade.

He said the announcement was completely unintentional but added that if not treated, glaucoma can cause blindness.

“I think anyone who reaches 40 should have their eyes properly checked,” he added.

The cycling accident was not the only harrowing event for the rock star in 2014.

In November, shortly before the cycling accident, a private plane in which he was traveling from Ireland to Germany lost its rear hatch but the pilot managed to land it safely.
