Hi and welcome to HCM.
It sounds to me like you have some subcutaneous lesion of abdominal wall. It is almost impossible to feel your galbladder and you would have crampy pain after meal. It is more like some kind of benign tumor
, lipoma, fibroma
, whichican be easily surgucaly removed.
If you think that this is intraabdominal then you must do ultrasound
and further examination.
Wish you good health.
