Hello. Since the end of December I have had a few bouts of nausea and two incidents of throwing up, but not much. I have been to the hospital and my family doctor and both agreed with Gastritis. I am on Protonix and Zantac. It seemed like when I ate pasta I felt worse so I quit that. And I've been eating a lot better. Most days I feel good, but lately I've had a tight/full and slight burning sensation a couple inches above my belly button. It feels almost like a knot. I have an appointment with a GI doctor this week. Could this be Gastritis? Something else? My fear is Stomach cancer. I'm 24 years old and have always been healthy, never smoked, love exercise. Can someone help me? I'm scared for my appointment and have a big fear of cancer
