Hello, I am 41 yr old male diagnosed with tinnitus which appears to be caused by some hearing loss (ENT says this). However, I often get numb feeling in one of my ears, and also, when I chew on something tough, my ringing (which is high pitched and CONSTANT) changes frequencies. If the ringing is made up in my brain, then how is it possible that chewing makes it change frequencies and volume? And what about the numbness? I think it might be more complicated than just some hearing loss.
