My DD (13) has had recurrent stomach aches/nausea for several years. They do not appear to be related to diet or anything else. Our GP has referred us to a paediatric clinic at our local hospital as she thought it could possibly be abdominal migraine. DD does not have any headaches but has "seen bright lights" a couple of times which sounds like optical migraine. I just wondered if anyone else's kids have suffered from abdominal migraine and if there is any effective treatment?
