My stomach has been hurting. how can i tell whether it is acid reflux?

Trial of medication: A brief answer is to try medication to reduce stomach acid such as Pepcid (famotidine) or Omeprazole would be helpful. The evaluation of abdominal pain as a general rule can be tricky and i would encourage discussing this with your physician to avoid missing a serious medical problem.

See your doctor.: Acid reflux (gerd) typically causes 'heartburn', that gnawing burning sensation in your mid-chest, often worse after eating and/or when laying down. It may be accompanied by difficulty swallowing, regurgitation of food, or even wheezing. It rarely causes abdominal pain.
