Be thankful they found it promptly! Gall bladder problems get REALLY ugly when they have trouble finding it. I went through it a few years ago. I had gall stones, but since my pain didn't present in a "typical" way, they never thought to check my gall bladder and it took them nearly a year of my having "attacks" before they figured it out. They put me on physical therapy for 6 months (this was right after my son was born it started causing me problems), when that didn't work, they checked into my heart, blood pressure, etc, and just kept shrugging their shoulders and sending me home. Finally one night I landed in the emergency room screaming in pain, and by then I had gotten severely jaundiced. One ER Dr had the presence of mind to draw a blood panel and see I was suffering from SEVERE pancreatitis and my liver and kidneys were shutting down - an ultrasound after that confirmed I had a gall bladder chock full of stones, and so much inflammation they couldn't even do surgery - I had to be kept on IV antibiotics and anti-inflammatory for 2 weeks in intensive care before they were able to do the surgeries. One surgery to remove the gall bladder, and a second surgery to remove the extra gall stones that had "fallen out" of my gall bladder and into my pancreas, and also plugged my lower bile duct. It was a good 3 months before I was up and about again - not a good thing when you have a tiny infant at home.
*hugs* to you and healing vibes - and as much of an inconvenience as it is now, be thankful they found it sooner rather than later!
