Hi Vickie!   I'm so sorry to hear your daughter is suffering! It sounds like at first, your daughter may have had what is called Silent or Acephalgic Migraine, or Abdominal Migraine, which is common in children.   You mentioned a couple of triptans you've tried, did you know there are eight all together? Maxalt, Relpax, Frova, Imitrex, Amerge, Axert, Zomig, and Treximet. If you still have not tried all of them, there is still hope one may work better for her then the one she is currently taking for Migraine attacks.   Also, sinuses and Migraine are not related. Migraine is a genetic neurological disease, treating it with antibiotics will do nothing. We have a great article here on the site: Sinuses Giving You a Headache? It's Probably Migraine.   You may want to consider seeing a Migraine Specialist, instead of just a neurologist. Migraine Specialists treat only patients with Migraine, not all neuological symptoms as a neurologist does.   Good luck to you and your daughter!!
