Right this is going to be kind of hard to explain but ill give it ago. There has to be an anatomical reason for what is going on but its pretty hard to explain but ill try!
Right can anyone do this thing where you what feels like is make your ear drums vibrate? That may well be what it is, ive always wondered what it was. It is like impossible to explain how you do it, you just do.
The best way to describe it is you sort of wince and you hear this noise that sounds like wind blowing past your ears, what feels like your eardrums tingle and it is quite a funny and pleasurabel sensation. You can only sustain it for a couple of seconds at a time
then it sort of fades off and you have to redo it again. Sorry if this sounds really weird just always wondered what it was! My hypothesis is it is the membrane over your ear drum vibrating, is this right?
How are you celebrating?
