I am 8 days postop and I'm on all liquids. Even though I can drink many different liquids without any reflux or problems... Plain water still makes me cough up this... foam...? Its white and foamy and I was told post op it was just anesthesia but now my doctors concerned and I have to suffer through an Endoscopy (you know the camera down your throat...) Any ideas or suggestions what this is about or what I can do to make water more tolerable b/c if this doesn't improve I can't move on to soft foods and I REALLY want to move on... Not to mention that I live in Al Ain, Abu Dhabi which, as some know, is in the MIDDLE of the DESERT. So water's kinda important... Please HELP!!!
