Stomach pain after eating

I had an endoscopy 4 weeks ago and they said i had cronic gastritis and esophogitus - basically a step before an actual ulcer. I've been on meds for 6 weeks and seemed to be feeling better. 2 weeks ago I started getting pain again after eating on my left side, right under my rib cage. I still have the burning also, but it's pain after eating and I seem to fill up with gas and the pain lasts for a while. I also get intense waves of nausea. I'm going in for a CT scan tomorrow morning, and should get the results next week. I  had an ulcer 2 years ago with similar symptoms, but I got better after being on meds. I'm on carafate 4x day (been on it for 5 weeks now), and protonix. I was on nexium for 4 weeks, but they switched me to protonix last week.

Anyone go through anything similar? I can handle eating bread and yogurt, everything else seems to make me hurt.
