My 10 year old is suffering intermittent headaches that last for a minute. He says it feels like something hard pushing out from the front of his head. It's so bad it makes him cry. The GP said to give paracetamol 4 times a day, but can't find anything else wrong with him. GP said at this stage A&E wouldn't do any further tests. What could this be, and how can I help him? He's missed 3 days of school so far and I'm worried.
