My oldest son had anal itch first a few years ago and then I and my husband subsequently had symptoms. We do get nasal itching as well so they are scattered. I have seen them on my kids bottoms and my myself. I have felt a strong itch on one specific area of anus and put on glove and literally taken a threat white worn looking thing off spot that was itching and itch subsided. I have no doubt it is pinworms. Thanks for any advice.
