My first question is, when was the last time you had a bowel movement? It could be a combination of gas and constipation. If this pain continues you should definitely get worked up by a GI doctor. If everything comes back negative you should consider enzymes and probiotics. These symptoms are very common when you're not producing enough enzymes to digest your food properly or don't have enough good bacteria in the gut. This happens as we age, when we are not eating the best diet in the world or if we are really stressed out. It's very easy to fix, however, taking a good healthy probiotic daily and enzyme with every meal can help eliminate these symptoms very quickly.
