I have been getting persistent cramps and stomach pains mainly in my lower abdomen, this occurs with bloating and also sometimes a shooting/tight pain under my rib cage. Sometimes the pain is so bad that I cannot stand up straight, and/or feel slightly nauseated. I find that this occurs after eating, and after drinking hot beverages, although the pains/cramps occur while i m not drinking or eating anything as well; often times the cramps are followed with gas. I am certain that I am not pregnant, and wanted to ask if this could be a severe digestion problem?
