8 weeks ago (sept 10) my husband had triple by-pass surgery, with his two main arties to his heart 95 % blocked, he had never been sick, and we were told that this was hereditary but he is doing much better now, except that he has all this phlegm that comes up all the time during the night he is up all the time spitting, when we walk, he is spitting all the time also. He said sometimes it is so bad it chokes him. He has had a chest x-ray, and all was ok, any suggestions, thanks barb :
