We previously reported that during the season finale of “Total Bellas” this past March Nikki Bella announced her retirement from WWE.

The Bellas appeared on Thursday night’s episode of The Tonight Show with Jimmy Fallon in which Nikki revealed that in addition to her neck issues, she also has a cyst on her brain which was also the reason she retired from WWE.

During the 3:25 mark of the interview (view above) Nikki told Fallon that she felt like she needed a check-up before she and Brie went back for the [Women’s] tag titles, however it came back that she had a herniated disc above where she had surgery that she also has cyst on her brain.

Nikki also recently spoke with TMZ Sports in a short video interview (view below) indicating that the cyst on her brain is super scary, but benign.
