Lewis Capaldi says that it's a 'real possibility' his Tourette's will force him to quit music

The Scottish singer says it only affects him when he's playing music

Lewis Capaldi's fly-on-the-wall documentary 'How I'm Feeling Now' lands on Netflix this week.

However, the Scottish singer has given a revealing new interview that sees him share his thoughts on the music business - and the 'very real possibility' that he will have to quit it because of his Tourette's Syndrome.

In an interview with The Sunday Times yesterday, Capaldi said that his Tourette's is only triggered when he is playing music, and that he may have to consider in the future whether it is worth it or not.

"It’s only making music that does this to me, otherwise I can be fine for months at a time, so it’s a weird situation," he admitted. "Right now, the trade-off is worth it, but if it gets to a point where I’m doing irreparable damage to myself, I’ll quit. I hate hyperbole but it is a very real possibility that I will have to pack music in."

Footage from his forthcoming documentary also sees him discuss the difficulties of his tics. "The twitches became out of control; it was awful, absolutely horrific," he said. "I started to get in my head about it - you know, these pressures about things. Rather than just me singing my silly little songs, other people are depending on me."

He added: "My twitch gets worse when I sit down to play piano, physically painful. And I get really short of breath and it’s like my back fucking kills me when I go to do it."

Having revealed his Tourette's diagnosis last year, he elaborated on how it physically affects him. "It feels like I’m going insane. Completely disconnected from reality," he said. "I can’t breathe. I get dizzy. I’m sweating, my whole body starts convulsing. Either I feel like I’m going to be stuck with it forever, or I’m going to die."
