Yesterdays after dinner my stomach started hurting I just thought maybe I ate too much but this morning I still have that stomach ache. It kind of feels like im sore or something it hurts more when im standing. What can it be?

Anytime I hear stomache aches or any type of pain in the stomache I advise everyone to have there gall bladder checked out. My pain started in the upper part of my stomache after I ate almost anything and the pain would go away after about an hour or two that would happen like 2x a month. Eventually the pain got so bad I refused to eat anything.....bottom line they did an ultrasound and it was my gallbladder.
