I agree. parasites are misdiagnosed as 'gall stones'. It happened to me. Long story short: My parasite problem became apparent after I developed Candida subsequent to Antibiotics . Pain began in left abdomen just to the side and below belly button. Diagnosis: gall stone (one specifically). Dr. wanted to schedule me for surgery. I have never had surgery so you can imagine my dismay. Did some research, found out about Andreas Moritz Liver/Gallbladder flushes. Did them according to instructions. Eliminated many over the course of 2 flushes, hardly any on third, then nothing on the 4th. By this time research on symptoms indicated Candida and Parasites. This is what is ailing me. I see the evidence in my stool and all symptoms corroborate this. Notice that my pain is on the left and the liver and gall bladder...? still that was the diagnosis. I believe this type of misdiagnosis is rampant.
