I sometimes develop pain in my lower abdomen that feels more like a cramp. If I eat something that does not agree with me I also tend to get diarrhea along with the abdominal pain.
This tells me that my stomach pain symptoms are related to a virus that is slowly working its way out of my system. I know some people complain of irritable bowel syndrome which are causes of lower stomach pain in children and adults.
They say that people with irritable bowel syndrome should avoid chocolate, large meals, alcohol, and drinks containing caffeine.
They also say that an increase in fiber along with medications such as dicycolomine and hyoscyamine help control muscles spasms and should be taken thirty minutes before eating.
