I'm not sure exactly how to describe this, as it's happening to my mother. In November 2006, she became very ill and ended up in hospital on a breathing machine for about 3 weeks. Ever since she's been home, she's been complaining about this "crap" on her throat. She'll start coughing and then gagging to the point of rocking in her chair. I've never seen what she brings up, but she says it tastes awfully bitter. She also had bad pneumonia while she was in hospital and at first she was told it was "leftover pneumonia" coming up. I don't think that's the problem now... it's been over a year and half now. I would just like some suggestions or thoughts of what it COULD be. Any help is appreciated!
