I make this annoying noise with my voice because it relievs the pressure in my throat for a few seconds . I am constantly making this noise to relieve the pressure.
I trying my best to imagine what it must be like to be an old man at 14, LOL! Is you humming noise a noise that is happening when you breathe out with more effort than normal breathing, or are you actually using your voice to make the sound? Also, I was wondering if you are experiencing any tightness in your chest at all when you are having these problems.
Tell your family that the best way for them to get you to stop the annoying behavior would be for them to take you to the doctor to see what is causing the problem, because the irritation is coming from whatever is going on with your throat, and it's clearly not your fault.
