I had my gallbladder out a week ago today. I was told that I had black, muddy sludge in my gallbladder. What exactly does that mean? I also hear that most patients who have lap chole s are back to normal in just a few days. I am exactly a week post op, and I still feel terrible. I am 34, no medical problems, 5 2, 110 pounds, and very active with my two children. Thanks!
