How do i find out if i have them pinworms?

Consider issues: U get pin worms by putting egg contaminated fingers in the mouth.The eggs travel through, hatch & begin to live in your large intestines.Living pw's crawl out your anus &lay eggs.If you get an allergic rxn to the glue like stuff the eggs are laid in, it will itch a lot. Mature worms are visible, white, thredlike & about an inch long. Rx is so simple & free of side effects many just treat on suspicion.
