Pinworms Symptoms

Many people have pinworms and don't have any symptoms at all.

• The most common symptom of pinworms is itching around the anus. It is worse at night when the female worm deposits her eggs on the person infected. This can lead to difficulty getting a good night's sleep.

• Pinworms can rarely migrate into the vagina or urinary tract in girls, causing irritation in these regions. This is very uncommon and usually goes away on its own.

• Pinworms do not cause belly pain, bloody bowel movements, fevers, or poor appetite. If you have any of these signs or symptoms, you may have a more serious condition and should call your doctor or visit the hospital's emergency department.
