Popping joints: what's happening & does it harm you?

This is a relatively common question and as a rheumatologist, I should probably have a good answer.

I didn't. But I now have a good video to point to when someone asks about popping joints and whether they are causing damage when they pop knuckles.

Thanks to Dr Ai Lyn Tan (@DrAiLynTan), a fellow rheumatologist, for sharing this video on twitter. I thought you'd find it entertaining.
