My son David came home early from school yesterday covered  Cruise 2006 122 from head to toe in bumpy rashes, they are all over his body, as well as his face. The doctor instantly diagnosed them as Urticaria caused by an allergic reaction. They look very much like a heat rash.

David had been having a pretty normal day at school and we have no idea how he became infected. He is a very healthy 17-year-old, and this has never happened before, it came totally out of the blue. He also looks very pale and drawn. What could he be allergic too? How will we find out?

It reminded me of when my younger son James fancied a day off school, he was only about seven at the time. I had always told him he could only be off sick if he had a high temperature or diarrhoea. One morning he asked me to feel his forehead, which was burning, and I used a Feverscan thermometer to confirm he was indeed poorly.

But it seems Dr Seymour had been conned. A few weeks later, James admitted he had put his forehead on the radiator to make it hot so it appeared he had a high temperature! It worries me that he is such a good actor, he certainly had me convinced.

He can’t be the only one to fake it, so what sickee scams have you done, and did you get found out?
