On top of everything else that's going on with me.. I've been dealing with another problem for so long now.

I've been round and round with Doctors, who say my ears look fine, have been given a nasal spray from one Dr who suspected Sinus problems, no luck.

I finally mentioned it to my Dentist, and he suspects TMJ and clenching/grinding in my sleep due to stress. He says the clenching can cause this Ear fullness and pain. and has suggested a mouth guard.

The only problem is, these guards to get molded and fitted to my mouth is ridiculously expensive.. and If it is not the root of this ear problem, I don't want to bother with it.

I can feel pain in that ditch right behind our earlobes, that's where I can feel this 'fullness' like inside the Eustachian tube.. and I'm constantly holding my nose and clearing my ears, but that only helps temporarily.

Can anyone relate? Shed some light on this? (I've had numerous jaw x-rays to rule out anything serious.)
