Re: How exactly does TMJ come about?

Your symptoms have presented similarly to mine.
Based upon my physical exam and a very thorough health history, my TMJ orthodontist thinks that a surgery I'd had not log before the symptoms presented may have been a trigger for me. He stated that intubation can be a fairly common trigger.
