'Big Bang Theory' Star Mayim Bialik Says She 'Can't Speak for a Month'-- Find Out Why!

Mayim Bialik is on vocal rest.
The 41-year-old Big Bang Theory actress revealed on Wednesday that she can't speak for a month because her vocal chords are sprained. Bialik tweeted a picture of her at the doctor's office, and relayed the bad news.
"Me waiting for a check up from my ENT. Can't speak for a month. Yup," she wrote.
But Bialik has the help of her 11-year-old son Miles to communicate with fans. The actress posted an Instagram video of Miles reading her messages out loud as she's typing them.
"This is my son, Miles, talking. I sprained my vocal chords and I can't speak -- it really sucks," Miles said on behalf of his mom. "So, we're having a silent video with me talking. I can't talk because my vocal chords are sprained."
ET spoke to Bialik last month about her book, Girling Up: How to Be Strong, Smart, and Spectacular, when she talked about just how much she's like her Big Bang Theory character, Amy Farrah Fowler.
