When I was young I passed tapeworm on a couple of occasions, and was too scared to tell my parents or doctor.
They were flat and white and i had to cut them as i couldnt pass them all at once.
I have read that they can live in the body unknown for years and cause serious problems if they get into major organs.
I have been fine for at least 12 years but am now worried that they may be in there... should I be concerned?
