Never had this problem before. today I felt wiggling sensation on my anus and a white, flat 3 cm worm crawled out of my anus. it happened 4 times throughout the day. I don't see the worms in my bowel movements but I felt them crawl out of my anus when I'm sitting. I managed to catch them with tissue paper and they look the same. I live in Ethiopia and I don't have easy access to health care. can you please tell me what kind of worm it is?
