I woke up this morning, ate sugary cereal and had more sugary foods, then felt a mild pain in my stomach. I ate bananas to ease the pain, and they did a little. My stomach still hurts a bit though, I'm a little bloated but I'm not burping. Last night I was bloated after eating and my stomach hurt the same way, and I burped a lot too. I am a young teen, not an adult if that helps.
