Brian took to Instagram to share the health diagnosis with his fans after getting an MRI scan to see where the source of the problem is coming from.

He explained: “I Had a lumbar MRI scan and finally discovered the root of the problem with my back pain!”

The 43-year-old shared a picture of the findings with the conclusion saying: “The L5 – S1 disc bulge with contact to both transiting S1 nerve roots.”

The L5-S1 is the lowest level of the disc of the spine, sitting at the junction between the lowest lumbar vertebrae and sacrum.

While it is not uncommon for the disc to bulge, it can cause terrible pain.

Brian explained his next step and said: “I just need to figure out what to do next.

“I’ve had it for years so I doubt it will get better without intervention.”

He captioned his post: “Big thanks to Pall mall medical for doing an MRI scan to finally figure out what’s wrong with my back.”

Brian’s fans all rushed to his post to wish him well on his recovery journey.

Natalie said: “Good news you finally have some answers. Fingers crossed they can find something for it to help you.”

Cristina wrote: “I am sure doctors will give you the best option for this. Please take care of yourself, and do whatever they recommend because your health is the most important thing.”

Claire commented: “It’s always good to finally find out what’s going on and know you’re not going mad!! Make sure you do as you’re told, your health is precious, as I well know.”

This comes after Mark Feehily was unable to perform five gigs of the Wild Dreams tour due to health reasons.

He previously battled pneumonia and it is unclear why he had to have surgery.

Mark had to take a few months off the stage to recover.

The Sligo native has recently reunited with his bandmates to perform on Good Morning America on Monday.
