Whats wrong with me...?

Lately I've had so much stomach pain. I always have to burp or toot. It doesn't really make me feel better but it's more like I can't control it. I have different pains in my stomach that rarely go away. Sometimes it's gassy bubbles, sometimes sharp pains, sometimes just sick feeling. I don't throw up but sometimes I feel like I have too. My stomach also makes gurgling sounds. I'm going to the doctor next week. But does anyone know what might be wrong with me?
