It may be worth going to your doctor as the symptoms can mimic many diagnosable conditions and without having baseline examination findings, it's hard to say what you're fighting off. Have you had any other gastrointestinal issues (fatty, floaty stools; diarrhea; vomiting; light-colored or clay-colored stools; etc.). outside of the cramping? Have you had an increase in symptoms after eating fatty meals? If you go to the doctor, you can get this treated (if it is bacterial) before it becomes a problem--or at least get labs run (such a amylase test for pancreatitis or GGT or bilirubin for conditions of the liver or biliary system) to rule out these possibilities. Unfortunately, cramping is indicated in far too many conditions to be indicative of one over the other. Indicators like stool consistency, referral pain (e.g. left epigastric pain, flank pain, right scapular pain...), etc. are helpful in narrowing down the the gamut of potential diagnoses. I'm not a personal fan of Western medicine for chronic disease brought about by modern stresses and lifestyle and environmental factors, but with acute emergent conditions, there are few other places to turn.
