What are the symptoms of pinworms?

Itching: Most common symptom is itching around the anus worst at night when the female worms lay eggs. The worms can sometimes move to vagina or urinary tract causing itching and irritation in this area as well.

Itching: We suspect pinworms when patients complain or, or are noticed, scratching their rectum. The pinworms are tiny white worms (about the size of a newsprint comma), that live in the rectum. Adult females leave the rectum and lay eggs on the skin outside the rectum. Look at the rectum, early in morning, and you may see the tiny, threadlike worms, or do a 'tape test' and have the lab look for the eggs.
