TMJ Pain

I have TMJ and it's normally very tolerable. But all of sudden it hurts to the point where I can barely eat or open my mouth without intense pain. The only way to get help is anti inflammatories which of course I can't take while pregnant. I'm 37 weeks. This is my 3rd baby, I am almost at the point of begging to be induced just so I could rid myself of this pain! Anyone else have this problem?
