I noticed that when I go to bed at night that when I exhale, I still hear air coming out after I'm finished exhaling, if that makes any sense. Someone said, its air coming out of my tonsils, but it feels like it is coming out from the back of my throat. I have been to see a ENT and he didn't know what it was, he gave me an inhaler, but it didn't do anything. Does anyone know what could be causing this, it feels really strange !!!!!!
