Hi Amy! You and I are in the same boat. My TMJ seems to be affecting my ears more than anything else. I have an appt. next week with an ENT. I am hoping he can tell me if my jaw is applying pressure to my inner ears or my inner ears are applying pressure to my jaw. I will post an update to my visit and maybe what I learn can help you as well.
Remember... most important with TMJ is posture. Sit up straight - now I guess we see in hindsight why parents made that such an important rule.
Make sure your chin is back and your neck is straight. Wear sunglasses so you don't squint - that really stresses the jaw. Do your best to sleep on your back more than any other position. If you drink coffee/tea in the mornings, I find it helpful to place the hot cup alongside my jaw when I am not drinking it. That way I can start of the day with a more relaxed muscle.
