Are you eating more aggressively? It's not uncommon that as healing progresses, we start eating more challenging foods that the stomach isn't ready for yet. In my experience, stomach aches are a symptom of stomach bloating. Can you burp at all? If so, be sure to try Gax-X or even Maalox to see if you can get the gas out. Otherwise you're just going to have to suffer the stomach pain until the gas exits the back door.
Also, if you're eating some veggies that might be more gassy, try BEANO. Take about 3 chewable tablets right when you sit down to eat. It can keep you from actually starting the gas.
Even now, when I occasionally get a stomach ache I recognize it right away as gas bloat, and take a couple Gas-X tablets. Give it a try and see if it helps. If not, then back off the food and eat the way you did at an earlier stage until you get feeling better again.
