Anal itching at night. No lesions, no anal sexual activity. Symptoms for 3 months. I was in contact with my little cousin who may have had pinworms 3 years ago. What can I do?

It is recommended to start with a cream such as Preparation H, which can be applied to the anus after each bowel movement and after showering. If the itching persists after 7 days of using the cream, it may be necessary to consider treatment for pinworms.
