As previously stated yes I had a blow to my jaw which also caused a concussion as well. And I have no reason to think I had a “hidden TMJ” as I had 0 jaw problems prior to this impact. I chewed gum daily for years prior to the impact and never even had slight jaw tension or discomfort. It would be silly for me to assume that I had a hidden TMJ when my jaw displayed 0 issues prior to a massive blow to my jaw where I instantly had clicking and tension resulted after.
