[Question] My jaw joint hurts when I chew hard or chewy food.

Recently, my jaw joint started hurting while chewing on squid.
It also sounds like sand being ground.
My jaw is uncomfortable, so I can't even open my mouth wide.
Sometimes I feel like my jaw is catching, or I experience a sharp pain.
There is no pain if I stay still.
Could this be a symptom of jaw joint disorder?
Will it be okay if I'm careful with hard things?
