I'm 46 years old. I weigh 145. I'm not on any medications. I do smoke. I recently had a 4 day bout with blotting and decided to go to the doctor. He suspected gallstones. He sent me for a ultrasound and they found (1) 1/2 inch stone. He sent me to a surgeon to have my gallbladder removed? I've been reading other peoples stories that had gallbladder attacks and they sound awful. I had no pain just discomfort. Is it necessary to have my gallbladder removed???
