Hello! Well i'm looking for someone to answer on my question for years now. Im 19 now, and as long as i know i think it started around when i was 6-7 years old. Well what happened ? I can control a low-frequency buzzing sound im my ears( well im not sure if it is ears but i suppose it is, i hear it in center of my head). Well i dont mind the buzz since i can turn it off and on as i want. But when i "turn it on " its not like switch, or wish, i turn it like moving an arm or leg, i dont think i just "use" it. One more thing when im using the buzzy sound i cant sustain it for long ... i can hear it for max. 15 sec and then i need to force myself to keep it going. One more funny fact is that i cant control the buzz when i yawn. I hear it every time i yawn. If i try really hard i can " silece it down" when i yawn but cant totally turn it off. So please tell me if this is some sort of sickness, what i dont belive since it doesnt harm me in any way. But i would like to know what this is.
