I am a 16 year old girl who has been suffering from chronic nausea, stomach pain, and acid reflux for over 3 years. It has gotten so severe that I can't even drink water without feeling like I'm going to throw up. The nausea is there when my stomach is empty, or when I've eaten. I can't eat a lot of food anymore, and I have to skip breakfast and lunch to make it through the school day without being sick. I've gotten practically every test possible (upper endoscopy, MRI, blood tests, etc.) and the only thing that has shown up is that there is inflammation in my stomach. My nausea has been affecting my life so severely, and I haven't been given any answers as to what could be the actual cause. Does anyone have any ideas on what I should do now, or what could potentially be the problem?
