2 night ago 4yo woke up twice saying his neck hurt. (Didn't think anything of it as he often wakes up with aches and pains and is always fine in the morning.)
Later that night he was awake for nearly 2 hours with a really bad headache and feeling as though he was going to be sick. (But wasn't) Gave him painkillers.
In the morning he seemed okay but said his head hurt a few times but seemed fine.
Last night, he woke up again with a headache, went back to sleep but woke up again and hour later with his head ache worse and needing painkillers.
He's otherwise well. Is going to the GP and over reaction?
