Queen guitarist Brian May has been diagnosed with torn spinal discs after undergoing a scan at a London hospital on Monday (16Dec13).

The rock icon has been struggling to recover from knee surgery in August (13), and he has also been suffering agonising pain in his buttock muscles since a performance at a Las Vegas music festival in September (13) that left him struggling to walk.

After having a magnetic resonance imaging (Mri) scan on his back, May has now discovered he is suffering from a painful spinal injury.

In a post on his Twitter.com account on Wednesday (18Dec13), the guitarist wrote, "My Mri says I have two torn discs, pressing on a nerve. Well, at least I know I wasn't imagining the pain now ! Bri thanks for yr (your) concern."
