I wonder if anyone could help or offer me some advice. My 6 year old son has been suffering with migraines since he was about 2. At first we thought he was lactose intolerant but at about 3, we took him to the doctors and he thought they could be migraines. Since then he has had a migraine every month or so, always following exactly the same presentation - colour drains from his face, he has to lie down, he vomits, sleeps, wakes and then is fine. However, about two months ago he started complaining of headaches that weren't migraines (he can actually differentiate between the two, but it is obvious when he is having a migraine attack due to afore-mentioned symptoms). These headaches come on suddenly but go equally as quickly and he can mention many times in one day that he has a headache. Two weeks ago we went to see the consultant paediatrician who said that he should stop eating chocolate and cheese, but this had no effect (and I didn't think it would, to be honest). Today we went back and the consultant has prescribed him Pizotifen with a follow up MRI scan. My question is, is it normally for the presentation of a migraine/headache to change? Can a child with obvious migraines suddenly develop a different type of headache? And what would they be looking for on a MRI scan?
By the way, we have ruled out other causes (problems at school, eyesight problems etc).
Many thanks for any help or advice you can offer :)
