Actress Jamie-Lynn Sigler recently opened up about her battle with multiple sclerosis (MS) and how she kept her diagnosis a secret from her Sopranos castmates for years. Sigler revealed that she first disclosed her MS diagnosis to a set doctor during a physical examination in 2001 but was advised to keep it confidential.
Despite not experiencing severe symptoms at the time, Sigler chose to follow the doctor's recommendation and kept her condition hidden from her colleagues. It wasn't until the final season of the show that the stress of a divorce and flare-ups from MS prompted her to confide in her co-star, the late James Gandolfini.
