I m worried about my 7 year old daughter, she keeps telling me she feels sick, over the last 5 weeks I have seen 5 different doctors due to her not feeling well, she was eventually put on antibiotics , but she still keep feeling sick, I noticed something at the back of her throat that dosn t look right, it looks like the tube going down from her throat is very visible, it looks like it is sticking up, why is this
