I don't know if this happen to you before but it did to me, sometimes ago mosquitoes fly into my ears in the night. It is very clear you can even hear the sound of buzz. My hubby has problem with one side of his ear because when he is young he has insect flew into his ear and even though the insect remove from his ear but he cannot listen well.
I just find out that David's wife also have problem with one side of her ear. Jen told me that she needs MYR$20,000 for the operation at Melaka hospital.
