Had No Problems with Tinnitus Until a Week Ago — Is My Clenched Jaw the Culprit?

I've had tinnitus for just over 5 years after going to a loud show and standing too close to the speaker. At first it was hard, but within a few months I had habituated, despite it being quite unstable for the first year or so (it would get louder and quieter, and even be painful sometimes).

I haven't had any problems with it since 2015 and only noticed it at night before sleeping or if I thought about it. Until about a week ago, when I started with a gnarly spike. It is loud and high pitched and really aggravating. Is this a thing that is going to go away or am I going to have to rehabituate to this? Is it even possible to do that if it gets worse like this? I am feeling scared.

Background info: I am currently having some other mental health problems and stomach issues, so my jaw is unbelievably clenched a lot of the time, if that could mean anything?

 

Very possible that it's just a spike, if you haven't been around loud sounds.

To give you an idea, I had a 2 week spike, thought to my suck f**k me... now I have to habituate again. But it went back to baseline.
