I just had a very heavy infection of pin worms. My stools were litterally covered in them and had a lot of blood. I took combatrin on friday but it seems they are still their a bit left so I took another dose. Is this ok or will it make me sick? Also I keep having this strange slight crawling sensation on my vagina and im worried they may have gone into my vagina. I have yet to see any in my vagina though.
