A reader recently informed us that she found a worm in her sink after blowing her nose, and has become paranoid as to whether it came from her or not. She describes the worm as being a wriggling, tiny thread; it was more than 0.5cm (0.2-inches) long and about 0.1cm (0.04-inches) wide.

A man recently sent in this photo of two worms he found after going to the toilet. After being very bloated for a couple of weeks and showing other symptoms, our reader went to his doctor who told him they could be pinworms. However, our reader does not think they look like pinworms, as he has had those in the past and they looked different.
