Christina Applegate is seeking answers about health problems after learning that her earlier multiple sclerosis diagnosis was incorrect. The actor is now investigating whether her breast implants could be causing her symptoms. On the November 10 episode of her MeSsy podcast, Applegate discussed the concern with co-host Jamie-Lynn Sigler. She said she had wondered whether her implants might be leaking and affecting her health. She had also received research about breast implant illness.

Applegate underwent a double mastectomy in 2008 after receiving a breast cancer diagnosis. She later had breast reconstruction with implants. She said the implants are overdue for replacement and plans to investigate whether they could contribute to her condition. The actor described severe fatigue, widespread pain and difficulty moving her right shoulder. She said getting out of bed can take around 10 minutes because her body hurts. She also described sleeping for long periods and struggling with everyday activities.

However, Applegate has not established that her implants are causing these problems. She plans to discuss the concern with doctors. No confirmed link between her implants and symptoms has been reported. The concerns follow her recent revelation that doctors told her she had been misdiagnosed with multiple sclerosis. Applegate first announced an MS diagnosis in 2021. She later said a doctor informed her that she did not have the condition.

The news left her uncertain about the cause of symptoms that have continued for years. She described feeling as though she had returned to the beginning of a difficult search for answers. Her symptoms have affected her mobility, and she has used a wheelchair for medical appointments. Applegate shared the earlier diagnosis update on her podcast, which she co-hosts with Sigler. Sigler has spoken publicly about living with multiple sclerosis. Their conversations address chronic health conditions.

She is considering explanations and seeking medical guidance. Reports say doctors are also considering conditions that can produce similar symptoms, including rheumatoid arthritis, lupus and Lyme disease. Applegate’s comments do not confirm breast implant illness or prove that the implants are leaking. They show she is examining another possibility while trying to understand her health. Further medical assessment will be needed before the cause becomes clear.

For now, Christina Applegate says she wants answers and plans to raise the implant concern with her doctors. Her latest update highlights the uncertainty that can follow a changed diagnosis when serious symptoms remain unexplained.
