You may find great peace after the gall bladder removal.
A friend's wife had constant problems...and finally, they decided to remove her gall bladder.
They said some/most have a number of "stones"... they have pictures of her's...it looked like a danged pomegranate (?) full of "seeds" all of them "stones!"
As for kidney stones...only knew folks with them and back in the day, they thought different folks were dietary related... after assaying the stone's passed.
With diet changes, they could reduce the occurrance. Is that still believed?
Prayers for your upcoming surgery to go well--- my friend's wife, while having many health issues, recuperated from that surgery very quickly!
Prayers too for no future kidney stones.
Keep the Son in your eyes!
