Hi , I am Dr Anshul Varshney , I have read your query in detail , I understand your concern.
It might be due to a stone in Common Bile duct, missed during surgery for Gall bladder
Getting MRCP is the best option to see for the cause.
You should get it ASAP, to avoid complications like Obstructive jaundice
and Acute Pancreatitis
This is my personal opinion based on details available here. If you want to discuss your issues further, you may please ask us
