You were correct to suspect a pinworm infection as the possible cause of your son's itch. He has not responded to the correct Vermox dose so this makes pinworms less likely.It is also rather unusual for a child of his age to complain about an itchy bum as well as itching of his hand and leg.Your son's symptoms are so definite that it is worthwhile asking his doctor to see him. Is it possible that he has been in contact with enamel paints or other paints which contain lead?
