"I feel great. I feel a hundred percent better. I’m just ready to get on the stage and start performing again," Mahone, 17, told PEOPLE's Raha Lewis at the American Music Awards.
"You know, I sing every day and when I had strep throat and I had that blood clot I couldn't sing at all for like, three weeks straight. It was torture," he says.
While he was ill, Mahone posted an Instagram photo of himself looking tired in a hospital gown with the caption, "I've never felt so bad."
But now that he's feeling well, Mahone couldn't help celebrating his health with a riff of "Human Nature" by Michael Jackson, singing "If this town, is just an apple, then let me take a bite."
