Can virus cause gallbladder attack? Spouse + myself had attack within weeks. Gallbladder pain followed 10 days of flu symptoms (body pain + fatigue)?

Gall bladder pain. Are you sure it is your gall bladder? After you eat a greasy meal, are you having right upper abdominal pains about an hour afterwards? If so, better see your PCP for u/s of your gall bladder. If not, better go see him anyhow for work up.
