Capaldi shared the news on Instagram Live, explaining that the condition is something he “constantly” deals with.
“The worst thing about it is that when I’m excited, when I’m stressed, when I’m happy, I get it. It happens all the time,” he said. “Some days it hurts more than others, some days it hurts less. It looks a lot worse than it actually is. Sometimes it’s pretty uncomfortable…but it comes and goes.”
He said his diagnosis “makes a lot of sense” after noticing he was having seizures in a 2018 interview.
“I often have shoulder cramps. When I see videos like TikTok, people think, ‘Why is he cramping?’ and that’s fine. Curiosity is fine. I did,” said Capaldi.
He continued: “It’s new. I haven’t learned much about it. I’m learning. I’ve got Botox on my shoulders to keep me from moving. It’s worked a little better.”
