They are often wrong.. the tests are unreliable and there are more peopl here with very active parasite infections but negative results. The pain could be Gallstones and while some peole may think they're harmless and easy to flush, that's not always the case. I tried to flush mine for 4 years with no luck and my gallbladder was so full of huge stones, it was starting to rupture... it screwed up my pancrease for a while and cause major damage to my bile ducts. Ask for an ultrasound to look for stones and blood work. Theore experienced people can tell you what to look for in blood work to detect parasites. Never feel guilty about seeking help. You only get 1 body.
