Mayo Clinic explains that the disease occurs when a shingles outbreak affects the facial nerve near one's ear. In addition to facial paralysis, it can also cause hearing loss and requires prompt treatment.

The clinic shares that immediate treatment of the syndrome reduces "the risk of complications, which can include permanent facial muscle weakness and deafness."

When Bieber revealed his health diagnosis in June, the singer said that his symptoms included being unable to blink one of his eyes and move his nostril nor smile on one side of his face.

"This is pretty serious, as you can see. I wish this wasn't the case, but obviously, my body is telling me I got to slow down, and I hope you guys understand, and I'll be using this time to rest and relax and get back to 100 percent so that I can do what I was born to do," he said.

At the time, he added that he was taking time to work on his health and was working on "facial exercises to get my face back to normal."

After resuming his Justice World Tour in July, which was postponed after the announcement, he performed six different shows before pulling the plug on his remaining tour dates.

"It took a real toll on me," he wrote in a statement shared on his Instagram Story in September. "This past weekend, I performed at Rock in Rio, and I gave everything I have to the people in Brazil. After getting off stage, the exhaustion overtook me, and I realized that I need to make my health the priority right now. So I'm going to take a break from touring for the time being. I'm going to be OK, but I need time to rest and get better."

Bieber continued: "I've been so proud to bring this show and our message of Justice to the world. Thank you for your prayers and support throughout all of this! I love you all passionately!
