Sam Smith has a throat infection and the pain is so bad it feels as though he has a "tennis ball" stuck in his throat.
The 'Writing's On The Wall' singer has been struck down with the illness and has been left in agony with his swollen glands.
In an Instagram post, he revealed: "Feeling very sorry for myself. Throat Glands are so fucking big. Feel like I have a tennis ball down my throat (sic)"
Despite his illness, Sam was able to unveil a cover of Amy Winehouse's 'Love Is A Losing Game' taken from 'In The Lonely Hour: The Drowning Shadows Edition' - the new special edition of his debut album - on Thursday night (05.11.15).
Discussing his decision to record the cover on BBC Radio 1 and his love of the late artist, he said: "I saw the film recently and, sometimes, people forget my age. I was 11 years old when 'Frank' came out and that album has really shaped me as an artist and my views on music and my relationship with music, lyrically. Seeing that film brought me back to that moment of being 11 years old - her rawness on such beautiful chords, on such expensive chords."
In May, Sam, 23, underwent voice corrective surgery at the Massachusetts General Hospital Voice Center to repair his damaged vocal cords and spent weeks under doctors' orders not to speak. He made a full recovery from his operation.
