I have lower stomach pain ( it s at by belt line, above my groin & 3-4 inches below the belly button, about center between my hips) that started before I got out of bed this morning & at 6:00pm it has sub-sited somewhat. The pain comes and goes in 5-8 minute intervolts. I have no fever, chills, vomiting, constipation or diarrhea. It s more painful when I sit rather when I stand. Yes, I have a belly, I m 6 foot tall at 215 pounds
