Many thanks for the query.
I have gone through your mail thoroughly and could understand your position. Muddy sludge is a powder like material formed and seen in the gall bladder
which eventually get hardened to form gall stones
. Sludge is more dangerous than stones as this material can get into the bile duct and can cause jaundice and pancreatitis
due to obstruction to passage of pancreatic secretions. Pain and abdominal discomfort are not common after a laparoscopic cholecystectomy
after 2-3 days after surgery. Pain abdomen a week after surgery would suggest a retained stone in the common bile duct or some pancreatitis due to residual sludge in the CBD, gastritis, duodenal ulcer
etc... You need to see a doctor and get some blood tests and an ultrasonogram of the abdomen to rule out any ominous cause of your pain.
