I Have Been Experiencing Stomach Discomfort On/ Off For Aprox.

i have been experiencing stomach discomfort on/ off for aprox. a week. no diarrhea or vomiting. not much of an appetite, bloating and a cramping of the stomach after i eat something. A low grade nauseousness in the upper stomach the appears several times a day throughout the day. i eat very healthy and do not eat spicy of fried foods. For the last 6 hrs. i have been feeling the best in several days. Able to eat a decent meal without any of the above symptoms. Is it possible that i have so type of stomach virus.
