Have a gallstone for over decade now never causes any symptoms for three days get stomach ages and my poop has been pale am i ok?

Please restate your question, it is confusing.

Pales stool can be a sign of gallbladder blockage. If having pain and you have known gallstone would follow up with ER so they can do an ultrasound to see if you have acute cholecystitis . Other causes such as pancreatitis, liver disease would also require ER assessment. https://www.medicalnewstoday.com/articles/324582

If you have pain the best thing is to see your MD to find cause and any relation to the stone
