Slayer frontman Tom Araya is still feeling the effects of his recent surgery - he has a constant lump in his throat.
The bassist went under the knife earlier this year (10) after he was diagnosed with a cervical radiculopathy, a dysfunction of a nerve root of the spine.
The operation has cured the agonising pains he suffered as a result of the condition - but it's left him with a feeling of obstruction in his neck, and he has to be careful not to lose his composure and start headbanging onstage.
He tells Metal Hammer magazine, "I went in and came out and I felt fine. The surgery was actually in my neck, although it's part of my back. They went through the front of the neck, moved the oesophagus and all that stuff out of the way, attached a plate onto the front of the neck bones and then put everything back. There are six screws in there.
"Afterwards I had a big lump there which disintegrated. I guess my body absorbed everything, although I still feel like I've got s**t in my throat... Dude, you don't know how bad I want to headbang when I'm onstage. I just can't, though - not ever. That's the real bum-out. I'll be up there playing the songs and I really want to do it, but I can't... I like playing the songs, and I can't do what I want to do!"
