Sorry boxerlover - it sounds like it's really swollen up there in your eustation tube area.
I don't hear crinkling, but I definitely have that muffled sound especially after I yawn. I clench and grind too.
Hey boxerlover, I was just asking Gloria the same thing I'll ask you. About hormones. Have you by any chance tried any HRT, or think that all of your head monster symptoms could be related to perimenopause? I am seriously starting to think this route - that it all has to do with hormones from hell. I've even read that the fluctuating estrogen and progesterone levels can wreak havoc on the vestibular system, and also of course cause migraines which by itself can cause so many horrible things.
