I have a strange scratchy irritation deep down in my throat / wind pipe, it feels like it is below my adam s apple at the base of my neck, possibly my trachea. It comes and goes some days it is not there at all. It feels like an itch and sometimes makes me cough. It has been like this for weeks and is very uncomfortable sometimes. I cannot tell what brings it on, sometimes it seems like when I am inhaling, but sometimes it still happens when I hold my breath.I am 31 years old, 69.8Kg in weight and about 180cm in height.
