Really really painful jaw!

[NeverSurrender]

Since I was a child my jaw has clicked out of place if I opened my mouth too wide but wasn’t painful.
The last few months it’s been really painful and now I can’t chew or open my mouth fully. It’s throbbing all the time and my ear feels blocked. My heard hurts all round my eye on that side too. I have been waking in the night with my teeth clenched together too
Anyone have any advice please?🙁

I’ve just been told I have tmj - have you looked that up? Started with ear problems and worked it’s was down my neck. My dentist confirmed. Might be worth looking into? x
