Why does it feel good to crack our knuckles?
gpt
The reason it feels good to crack your knuckles is because pressure is being relieved. Just as when any of your joints crack, gases are being released from within the synovial membranes. This release can cause a temporary relief of pressure or pain. In most cases though, the pressure or pain will return.
