All:

I could really use your thoughts and expertise. For the past week and a half (give or take), I have had relatively persistent upper abdominal pain. It fluccuates from almost non-existent to nearly doubling me over. I'm leaning towards believing that I have the onset (or a full-blown) ulcer, but as I've never had one before I'm not certain. Where I'm at on my diet is that I started transitioning the beginning of October to more of a Primal diet. Before the end of October, I had just about eliminated all starchy carbs and grains. Is there any chance that I haven't given myself enough time to segue into the Primal diet, and I've messed something up? My protein intake has increased substantially since mid-October, and I'm just wondering if my system has had a hard time dealing with it.

Thanks for any and all thoughts you bring forth.
