My wife had her gall bladder removed because she was developing stones. It is actually more common than you think and hard to diagnose because of the location. Many people think they have an ulcer or something stomach related, but the sharp pains do not go away. The risk is if you develop stones, you will have bile backup into the liver and develop liver damage.

Go back to your doctor and request a blood test if he didn't do it already. If your liver enzymes are elevated, you need to have a scan of your bile ducts to see if they are blocked. If not, for prevention, eat less fat. The gall bladder stores bile created by the liver and uses the bile to digest fats. Less fat or less fat at one sitting, less issues.
