I do have TMJ and I do have tinnitus, but I dont think this has to do with either of those. With the TMJ I get a loud poping sound in my jaw everytime I chew and I do get ringing in my ears which is the tinnitus.

I will see if the throbbing can be due to tinnitus, but it seems to be different in nature. I will try the methylcobalamin lozenges to see if this has any effect on it, ty.
