It does sound more like pinworms. The best treatmet is to paralyze them and get them out of you with a laxative. If you take the pills that kill them the eggs hatch in you and you get infected worse. Take pyrantel every day for a week and then once a week for a few months after that. Do lots of enemas.You can add some clove oil in to kill any eggs that they lay in the tiny folds of skin in your rectum. Practice all the hygiene, wash sheets shower every morning and wash the area with lots of soap and water. Clean toilets with alcohol after each use. Keep the area coated with vicks all the time is best but especially at night. They are hard to get rid of totally. You get easily reinfected from household dust.
