Hi, I'm a 15 year old male. Friday, I went out to eat with my family, when we left the resteraunt, I felt fine, but after about 45 minutes, I got a horrible stomach ache. I layed down and I felt like I was going to throw up, and I could only sleep in 45 minute spurts. All of the sudden, my stomach started to feel better, so I fell asleep for a suffiecient amount of time. When I woke up, I felt just fine, until about 20 minutes later, my stomach started to hurt again. I layed down the whole day. Something wierd happens though. I get hungry a lot, but if I eat something, my stomach starts to hurt worse, and I feel like I am going to throw up again. My dad said that he thinks that I had a stomach ache Friday because I ate too much, and now my stomach aches because I haven't eaten enough. He also said that the reason my stomach hurts worse after I eat is because it is in "shock" of getting food when I haven't eaten in very long. I did go about 21 hours without eating anything before I ate a banana. I've only eaten bananas, toast, and nutrition bars. But, still it continues. This is the 4th day, if you include Friday, but if not, it's the 3rd. I missed school today because I didn't feel well and I haven't eaten a meal since Friday night. Can anyone tell me what might be wrong and if my dad is right or not? Thanks
