About three years ago I had two ultrasounds after experiencing terrible pains in my left side. The doctors concluded that my gallbladder did not expand and contract correctly. I was told that I could choose whether or not to have surgery, so I took a week or two to decide. During that time my pains disappeared and have remained gone for the past three years. Just recently I have been feeling extremely nauseous and the times that I have thrown up it is always bile. I normally have a strong stomach and have not been exposed to any stomach viruses. I was wondering if my gallbladder could be causing this.??
