If you are having pain after gall bladder surgery then it can be due to acidity, hepatitis or liver infection, duodenal ulcer, adhesions, or due to an abscess inside.
Liver function tests along with pancreatic function should be assessed. Consult a doctor to treat acidity with antacids and drugs like Omeprazole along with diet control.
Adhesions can only be known on laparatomy.
Do discuss this with your doctor and get yourself examined. Take care!
