Although at the beginning of my infection I had subtle symptoms, slight rash I never had before, dry hair, Extreme fatigue, brain fog.....the dark circles were a definate puzzle to me. I might get them in the past when I lacked sleep, but they would generally clear up by 10am. Then suddenly they were prominate all day, even after sleeping more than usual (since I was so tired).
Several months later I found the worms. I thought mine were inherited, but they are totally gone now.
