I am a healthy 31 y/o female with no real history of serious health issues. Last year, however, I had repair done on a volvulus and I have had nothing but problems since. Recently, (one week ago) I began to experience severe pain that was localize to the right of my belly button, tender to the touch, felt like a gnawing pain perhaps? After a week of deal with this, my PCP told me it could be an ulcer. I was not so sure so I called on my Gastroenterologist and he suggested a CT scan along with two possibilities: 1. Hernia (due to the protrusion on my abdomen between my belly button and sternum; and also 2. Scar tissue which is interfering with the normal process of the digestive system. I'm slightly worried as this isn't my first dealing with stomach issues. Given the possible theories, which would you say are more likely?
