And it looks like she's still having problems with that area of her body.
On Saturday, LeAnn took the stage at the Choctaw Casino in Oklahoma but had to cut the show short due to jaw pain.
After the show, she tweeted:
Oklahoma!!!! I love you so much! I'm sorry for no encore. I had my jaw pop out of place & I can't hear out of my left ear. #tmjsucks— LeAnn Rimes Cibrian (@leannrimes) March 23, 2014
I can definitely feel her pain ... vicariously anyway.
