My butthole itches at night... do i have worms?

Maybe: Pinworms like to come out at night, lay eggs around the anus, irritating (itchy at night and usually other times too); makes you scratch, get your hands infested, touch your mouth swallow eggs, and get more (yucky, but clever adaptation on their part) could be other stuff, unrelated. See your doc, get checked.

Itchy Butt; Caffeine: Is the most common cause of anal itching not hemorrhoids as stated win the ads. Pinworms can be another cause usually in children after playing in the dirt. But cokes, coffee, tea, chocolate, and energy drinks like red bull have lots of caffeine leading to severe itching and bleeding, even waking you from your sleep at night clawing at your bottom. Stop the caffeine!
