Last month, Dion shared more details about how difficult her life has become with stiff person syndrome, which can cause involuntary spasms and muscle rigidity, while promoting her new documentary “I Am: Celine Dion” released on Amazon. In an interview with NBC’s Hoda Kotb at the time, the singer said trying to sing with her condition feels “like somebody is strangling you.” The spasms can attack different parts of her body, including her abdomen, spine and ribs, she said. “I have broken ribs at one point because sometimes when it’s very severe, it can break some ribs as well,” the Grammy-winner shared.
