OMG, they had the CT of the head, and they did not comment anything about the TMJ. I would demand the CT results - actual CD disk with data and review it myself, you would be able to see your TMJs in their after some practice if you want to get to the bottom of this. ER mostly check for something big and serious, internal head bleeding, big tumor. So small changes such as slightly damaged condyle of the the TMJ is not impossible, especially the sounds you have - sounds like fluid in the joint? How about cracking, popping, more like cartilage kinda noises as if it was being torn (which is not) but that's what it feels like when I open my mouth most of the time. Even moving the neck, head position change, triggers popping, as if some bone was out of place. Doctors sucks, they put you on klonopin, well good thing that it does help with facial pain, but unerlying condition - few one to touch it...
So it looks like it's going to be a journey, especially if doctors have noted you to be anxious - who knows, they might just write down - hypochondriac and tap you on the shoulder; so don't express your anxiety or worries, but tell the doctors exactly how this condition is impacting your life, your ability to study, socialize, eat food... and be repetitive and annoying, maybe they will be nice and prescribe an MRI of the TMJs which I think is necessary to determine what's happening there.
May God help as all,
