Is it possible for worms to escape the body through urine? I happened to look in the toilet after urination, because it seemed unusually hot. I saw this awful gray-black inch long very thin (almost hair-like) worm actually SWIMMING in the toilet! I am hoping it came up from the pipes? How is that even possible? I have been to Mexico 3x in 2 years. Also the Dominican Republic. I did come back from there a little sick. I have a lot of unexplained gas and bloating. I attributed it to food sensitivities. I also grind my teeth terribly at night. I have intermittent anal itching, but I thought maybe that was hemorrhoids. Help! Live worms in urine? Really?!!
