I am a 16-year old male with many questions. I have been "sick" for nearly 4 months, and haven't quite figured out what is going on. I am having stomach problems such as: constant nausea, stomach cramps, the feeling of something being stuck in the throat, watery stools, weight loss, loss of appetite, uncontrollable belching. These symptoms are occuring all day, every day. I need to know what's causing this because I am very worried for my health. I have never had these symptoms before, and have tried various times to stop them with medications like Prevacid. The medications are not working and I am becoming afraid to go out in public because I feel so sick. What disease/illness do I have? How can you treat it? Will I be able to function as I did years before this happend?
