TMJ Pain

Not sure if this is the proper group to post this in. I am having tremendous trouble with TMJ. A couple of weeks back I broke out my pregnancy pillow and I must have done something to my jaw. Its been 2 weeks of pain on one side only. It cracks, crunches, etc. It hurts to eat and open my mouth wide. My throat and ear have minor pain now, too. Any exercises or advice? Does this just need to heal on its own?
