Re: What causes a fizzing sound in the back of head?
mine was tmj..got the soft splints and it was like a miracle.I had the back of head noise thing and tinnitus. Very annoying sensation and feeling, but thankfully fixable. I had gotten a root canal and it started after that. Luckily i had known someone who knew and had the same thing happen to them. Hopefully your feeling much better, but be sure to see a maxillary surgeon who specializes in tmj, cause otherwise they will not know what your talking about.
