Bill Rodgers, You describe the head noise, beautifully. My childhood home was in the woods of south Florida and I remember with some nostalgia the sounds of night in the country. For a couple of years before my diagnosis, from time to time, I noticed the ringing/electrical buzz sensation in my ears. In fact, when we moved into a new house I spent a whole night looking for a possible electrical problem in and about the house that might be the source. In retrospect, of course, it was all in my head! It, indeed, sounds like a high pitched buzz like you would hear on a summer's night when all the tiny tree frogs are auditioning for the critter's choir. And it sounds like the high hum of electricity going through high voltage wires. I have never had it explained and I have never complained to the doc. Interesting, sometimes I can initiate the sound by chomping my teeth together. I can get the buzz to a higher pitch by closing my teeth and then increasing the pressure on the teeth by tightening the bite. Try that! If it works, perhaps we can find others and have a head jam and go to Nashville and make a record. In all seriousness, let me know what you find out and I will remember to consult with my neuro. I 'm sure that the doc will confirm that it is all in our heads. Think of it as a free buzz! Jack Xekaxm 53/4, your PWP brother in pain and gain.
