Guy Sebastian shocked fans this week by revealing he has undergone spinal surgery after suffering from ‘nerve pain’.

The pop star, 43, took to Instagram on Saturday to share that he was recovering after undergoing surgery.

Guy shared a photo of himself lying in his hospital bed, complete with a catheter in his hand, revealing he had been in immense pain before the procedure.

Despite his predicament, Guy gave his fans a cheerful thumbs up in the image.

Captioning the post, Guy revealed that he had been experiencing unbearable nerve pain in his spine.

‘They say it comes in threes. There’s been a lot of highs this year but it’s also been a year where I’ve had to manage a LOT of physical pain,’ Guy wrote.

Guy Sebastian, 43, shocked fans this week by revealing he has undergone spinal surgery after suffering from ‘nerve pain’.

‘The worst of it has been this nerve pain in my spine shooting down my right side. I wouldn’t wish this pain on anyone,’ he continued.

‘It just never stops and it’s all-consuming, while trying to work, travel, do gigs etc.’

Guy added he was pleased the surgery was completed and he looked forward to making a full recovery.

‘I am, however, so grateful for the fact that I have been able to have spinal surgery yesterday. I hope it gives me relief and the strength comes back in my arm,’ he wrote.

‘My goal is to get all of this sorted and bounce back hard for tour early next year. I’ll get there and I will get it done but wow, in a fair bit of pain right now.’

The post was met with an outpouring of well wishes from friends and followers including Channel Seven star Larry Emdur.

‘All the best buddy, like everything else in your life you’ll smash this… and you’ll have a real-life battle scar,’ Larry wrote, referencing Guy’s 2012 hit Battle Scars.

Home and Away icon Lynne McGranger also jumped in with: ‘Sending love and healing vibes honey.’

Nine entertainment guru Richard Wilkins also offered an encouraging: ‘All strength to you Champ! Much love to all.’

Sunrise weatherman Sam Mac also offered his best wishes with: ‘Get well soon my friend. We need you fighting fit for the next few weeks.’

It’s certainly been a rough year for Guy, health-wise, with the Australian Idol star kicking off the year with a shocking ski accident.

Wife Jules took to Instagram in January to share that Guy had torn his calf muscle while skiing, revealing he won’t be taking to the slopes any time soon.

‘He’s out. Torn calf. Middle-aged man injury,’ the 45-year-old wrote.

Jules later shared a rather ‘smug’ photo of herself posing on the side of a mountain while dressed from head to toe in ski gear.

Then, in May, Guy was rushed to hospital after he suffered another shocking injury that saw him requiring surgery for a ruptured Achilles tendon.

The incident occurred after Guy teamed up with AFL great and radio host Brendan Fevola to help struggling club Masala Dandenong break a long losing streak.

The spinal surgery is one of many injuries and health concerns Guy has suffered this year

However, Guy’s afternoon was cut short by injury, with the pop star seen limping from the park in the fourth quarter.

Guy took to social media after the match, writing: ‘Thought I’d strap on the boots after a LONG hiatus, and performed for the locals.

‘Great day out for Masala Dandenong getting their first win with @brendanfevola25 kicking a bag!

‘Unfortunately I’ve done a proper number on myself. #realitycheck #sticktosinging #footyglorydaysareover.’
