TMJ can cause tinnitus; specifically there is a nerve connecting your jaw to the areas near your ear. Damage to this nerve, e.g., caused by years of unmitigated clenching/grinding at night or by an injury, can cause this. A neurologist may help suggest some tests. In the case of TMJ, there's a specific CT scan that will identify damaged cartilage below the ear that is typically linked to tinnitus.
TMJ was the cause of about 7% of my migraine.
Watched a few YouTube videos, self massages for a few days. Found a spot that was super painful. Once it released, Migraines mostly gone.
When you say “unmitigated” do you mean via a mouth guard or something else?
I clench, have a mouth guard, but still clench. Don’t know of other treatments but would love to find one. I have tinnitus either as a result or from a bike accident which hurt my jaw and started the clenching.
I have mild tinnitus. When I move my jaw forward the sound intensives strongly, and then fades when my jaw relaxes. So there is definitely a connection for me.
