Why does my partner cough when she puts a swap contained by her not here ear when it get itchy?

The thing is this does not come to pass with the right ear, lone the left.Why does my partner cough when she puts a swap contained by her not here ear when it get itchy?
It's a short time ago a simple reflex. Maybe the nerves in her vanished ear are more sensitive than the right.
Surely we all do? A serious newspaper clip works best...
I got this when I be young. Its the bodies antipathy to expel the foreign body (the cotton bud) and the best it can come up with for getting something out of the ear is coughing. I suppose it works because you move your director and therefore your ear. lol clever really.
Its nought to worry give or take a few, my mum used to put a little bit of moisturising cream on the bud and it stopped 90% of the coughing. Only a tiny bit though, otherwise the ear wax wont stick to the bud. Seems childish but it works.
That's completely commonplace. we all own cough receptors in ours ears that are sensitive to touch, much approaching those at the back of our throat. Its a opening of getting dust etc out, because when we cough the pressure in our herald forces some air and dust out of our ears! If it doesnt crop up in the right ear later she's probably just not tickling it the right road lol, receptors and our ability to accomplish them with a touch coton bud vary. It may work if you try it too!
p.s. take care putting anything in your ears, they are extremely petite, it may be better to moisten the swap with a bit of wet!
