In an emotional NBC interview, Celine Dion reveals the debilitating impact of stiff-person syndrome on her singing career and daily life. Describing the sensation of singing with the condition as feeling like being strangled, Dion explains how the spasms affecting her larynx and pharynx can be so severe that they result in broken ribs. This rare condition, affecting only one-to-two people out of every million, causes debilitating muscle rigidity, spasms, and profound physical limitations. Dion's struggle with stiff-person syndrome forced her to cancel her European tour, and she continues to work towards regaining her strength. Despite these challenges, she made a surprise appearance at the Grammys, receiving a standing ovation. This revealing interview sheds light on the harsh realities faced by those battling stiff-person syndrome and showcases Dion's resilience in the face of adversity.
