this mucus in the back of the throat ailment, appears to be something the doctors in the U.K. are unable to diagnose, they also put it down to allegies etc, is very distressing, particularly when you lie down, it feels has though your throat will block up and you can no longer swallow or breathe. Is it the result of one of these unusual colds we seem to get nowadays which have a long term effect on our immune system, I don`t know but I would like to, is there anybody out there who will help?????
