my cousin and I have been taking turns taking care of our elderly aunt, who is 79. she has spells where she has dry heaves and chokes up a bunch of phlegm. and all day long she's spitting up phlegm. doesn't matter if she's sitting upright or not. she can walk around, however she's getting weak because food doesn't taste good to her. says it has a metal taste, or just doesn't set well. she really wants to eat, and tries. so far she's been given 2 kinds of nausea meds that do no good. next up they want to scope her esophagus. has anyone seen this before and is there anything that can help?
