Parasites are microscopic, I didn't see it. They just ran the tests for it. My regular Dr. freaked out, and was like, "Oh my gosh, have you been out of the country blah blah??" :scared: But then the new Dr. said it was sooo common. I would never have thought I had a parasite. But my stomach issues were so bad, i was starting to worry I had cancer or something. I was relieved it was only a parasite.
