Blood pooling in throat - Tests negative

[bbird]

In the past 8 months, I have had blood pool in my throat 4 times .   One time, I awoke chocking because of the blood in the throat.   I AM NOT COUGHING - it is like the blood just suddenly appears.  I have had several tests including a cat scan, a chest x-ray, sinus CT scan, blood tests and a bronchoscopy.  All test results come back normal.   I was a smoker but quit 20 years ago.  Why can't my doctors find the source of this blood?   It is bright red and has several small clots in it - it is at least a tablespoon of blood.  Please advise what I should do next or what test I need.

did you see a ear nose and throat specialist? if not you need to start there, is it happening while you are at the dr?

CANT SAY I EVER HEARD OF SUCH A THING, BUT TO ME IT SEEMS LIKE YOU NOSE IS BLEEDING DOWN YOUR THROAT WHILE YOU ARE LAYING DOWN?? DO YOU GET NOSE BLEEDS OR HAVE A DRY NOSE?

This has happened to me twice now, and I had all the tests you had.  Did you ever find out what was happening to you?

It only happened once while I was laying down - the other three times it happened while I was sitting up.   My nose is dry, plus all three doctors checked my nose along with everything else.   I don't know whether to be worried about this or not.
Thanks for your comments.

DO YOU THINK IT MAY BE FROM YOUR NOSE?
