I am having abdomenal pain lasting at least a day with bloating. Usually it is related to something I ate such as certain corn type chips. If I eat or drink anything during this time, the pain increases to the point that I can t stand up straight. My abdomenal muscles feel as though they are spasming. Usually, it goes away after I sleep the night though often my abdomen is tender. I can eat some greasy foods with no problem. I am also lactose intolerant which I have always thought might be the problem. It does not happen every day. Maybe an average would be once a month. Lately I am thinking it might be more than just lactose intolerance as it happens when I eat foods with no lactose. No diarrhea. I lean more toward constipation. Any ideas about a direction to consider? Thanks
