Rocker Jimmy Barnes has suffered another health setback, forcing him to reschedule shows to recover from unexpected surgery.

The 66-year-old went to hospital on Friday night and was told he needed to have a procedure to address “unbearable” pain in his hip, Mr Barnes posted to social media.

“The doctors have recommended a remedial medical procedure ASAP followed by some physio to address the issue,” the solo artist and Cold Chisel front man said on Instagram.

“These doctors don’t muck around! Providing all goes to plan, I’m expected to make a full recovery in six weeks.”

Seven months ago he underwent open-heart surgery due to a serious bacterial infection.

Barnes returned to the stage at Bluesfest in March and was due to perform solo shows in August and September, however they will be postponed.

“I hate to let everyone down but I’m also never going to compromise the quality of my gigs,” he said.

“I apologise for the inconvenience this will cause everyone – I HATE moving shows! – but thank you for understanding.”

Ticket holders will be contacted once details for the new shows are in place.

Cold Chisel is due to embark on a sold out nationwide ‘Big Five-0 Tour’ tour in October to celebrate the 50th anniversary of the iconic rock band.
