I had the same issues for year but no pain so I figured it wasn't a big deal, I often asked the doctors if my ears were dirty cause of the iching and poping. I was always told your fine go home. I grind my teeth all the time in my sleep, tho I didnt know that I did until my husband woke me and said stop it!
Recently I starting having REALLY bad pain out of nowhere so I figured I got an ear infection. He said I've more then likely had this for many years. So I guess my point is just cause it doesn't hurt now or hurt bad doesn't mean your not affected like the rest of us. So keep coming back for help whenever you need it. If I knew more about TMJ I would tell you about it, but I don't. I also don't suffer near as bad as some people here, but Id like to still think Im a part of it all.
