Gall Bladder
Mary, I had my gall bladder out in 2000, after weeks of unexplained pain, unintended (but welcome) weight loss, and general malaise. I went to a few different specialists before they figured out the problem; I didn't have gall stones, but rather the gall bladder was having spasms that caused pain. I still have occasional discomfort, but nothing like it was back then. I hope your surgery is as successful as mine was! Best wishes to you.
