Hi I help out at a local nursery and two of the toddlers have worms, now every waking minute is spent thinking about these things, have I got them, will I get them, I do not have an itchy bottom, although I can make this happen if I think about it too long, what are the symptoms and do they do on there own. Thinking about just getting some tablets from a chemist, but what do I ask for and will I do harm if I do not have them. I do not think these adverts for "monsters inside you" are helping. Any help greatly appreciated.
