Symptoms
Folklore is filled with fantastic descriptions of symptoms and abnormal behavior attributed to pinworm infection. In fact, many people have no symptoms at all. Of those who do, the symptoms are usually mild and barely noticeable.
The movement of egg-laden female worms from your anus to deposit their eggs will often produce itching around the anus or vagina. This itching may become very intense, interfere with sleep, and make you irritable.
