Terry Crews' wife Rebecca King-Crews is opening up about a very difficult health battle she's been secretly facing for over a decade, and the revolutionary progress she has made. The couple appeared on Monday's episode of Today to reveal Rebecca has been battling Parkinson's disease since 2015. Wow! She first noticed some "slight numbness in [her] left foot" around 2012. Her trainer then noticed her arm "did not swing" when she walked. Then one morning, she woke up, and her hand was shaking. She knew it was a tremor because her grandmother had experienced them.
