Hi sdobko,
Thank you for reaching out to us - we're glad you're here! I am however, so sorry to hear about your son, that's frustrating.
It's not uncommon to have recurring migraine attacks. Has he been referred to his doctor for an exam? If not, that's the first place I'd start - with his doctor.
When my son was about nine years old, he began having recurrent migraine attacks. I (we) kept a detailed diary for three months, maybe longer it was about 13 years ago, and discovered what his strong triggers were. They included dark chocolate, dehydration, irregular sleeping patterns, skipping meals and getting overheated. If you haven't kept a detailed migraine diary I would encourage you to keep one. Let me share this information on migraine diary's with you; https://migraine.com/blog/keeping-migraine-diary-basics/ and our section on children and teens; https://migraine.com/blog/keeping-migraine-diary-basics/.
I hope that helps, keep me posted on how he is doing,
Nancy
