Christina Applegate pledges MS advocacy after saying she was misdiagnosed

On a new MeSsy episode, Christina Applegate promised to keep speaking out for the MS community after recounting that a doctor told her she does not have the disease, Good Morning America reports. She said it took 10 minutes to move off her pillow, get out of bed and stand, and that she now keeps a walker beside her bed. Page Six reports she plans to see a rheumatologist as she seeks answers.
