DS (6.11) has been complaining periodically for a couple of months about tummy pains. When asked where he points to his belly button. He is not constipated, still eating fine, hasn't been sick (although he has had a couple of incidents of what DH charmingly calls 'chunky burps') and it seems to come and go - but when it comes it is bad enough to wake him up, and he normally sleeps like the dead, and in the daytime can sometimes reduce him to tears.
Someone suggested abdominal migraine, which I had never heard of. I plan to book him a GP appointment during half term, but in the meantime I would be very grateful for anyone else's experiences on this - diagnosis, symptoms, triggers, and treatments...
