Sometimes It Feels Like My Tinnitus Almost Stops When I Bite My Lips

I have this bad habit of picking bits of skin off my lips. I usually do it with my fingers.

But sometimes when I use my mouth and teeth and not my fingers to bite or pick my lips.

I’m not sure what muscles are getting pulled in my neck or face when I’m doing that, but sometimes I get this split second Oh! feeling and it’s like my tinnitus almost switched off for a millisecond.

Is there anyway to find out which muscles I’m using or someone I can see to investigate this?

 

My tinnitus changes pitch when I clench my jaw. No better no worse. Only wish it would quiet down.
