My little boy keeps getting tummy aches but the doctors at the hospital can't find anything wrong with him.

They just advise me "not to panic". He has had lots of tests. Should I take him to a specialist in London, in case he is suffering from some serious disease?

I think this would be a waste of your time and money. Studies carried out in Sussex have shown the great majority of children with recurrent tummy ache don't have anything serious wrong with them. Most of them grow out of the problem.

It's good the hospital doctors seem to have ruled out any major diseases. I'm sure you can rely on their advice.
