Twitter users have suggested everything from acupuncture to full-blown back surgery.

As it turns out, though, the singer already has quite a bit of experience managing back pain.

Adele explained toThe Facein 2021.

“I slipped my first disc when I was 15 from sneezing.

I was in bed and I sneezed and my fifth one flew out.

In January, I slipped my sixth one, my L6.

And then where I had c-section, my core was useless.”

It really was just a metaphor for surviving," she explained.
