I am absolutely disgusted. Last night after my shower I was peacefully reading in bed when I felt a discomfort/tickle around my "foofoo" area (sorry about nickname, not sure how to call it on here).
I went to the bathroom to inspect what was going on, and to my horror, I found a short, white, thin, cotton like worm moving disgustingly.
I quickly showed DH in disbelief and flushed it down the toilet shortly after that!
We naively didn't know what it was and were horrified but now after having Googled it I know. It's threadworms. 
How come it's the first time I've ever heard of them? I went to the pharmacist who kindly explained everything and gave me something called Ovex for the whole family just in case and she said it was extremely common and that 40% of children got it at some point before the age of 10.
I am now assuming that they've got them too (otherwise, where have I caught them from?), so will treat them and DH when they come back from school/work.
I knew about nits which my kids have never had but worms! I vaguely heard about them when my gran told me that my dad caught them once as a child, but I thought it was rare and that it only used to happen in the olden days.
Anyway I've desinfected the whole house, changed all the sheets, hoovered everywhere, changed all the towels and will have that pill later with them.
Hopefully that will be sufficient to kill the worms and eggs.
Has anyone had Ovex, is it effective?
