Suggest Cure For Migraine

My 12 yo old daughter had what I believe to be a migraine this afternoon. Started with ocular issues in just one eye then quickly she had an absolutely horrible headache and light sensitivity. I gave her Imitrex which was prescribed when she had a similar migraine a few months ago. She had to lay in her room in the dark with a cold cloth on her head and was in so much pain for 2 hours crying bc iher head hurt so bad. I tried my best to keep her calm and relaxed knowing crying would make it worse. She finally fell asleep, woke up after 15 min and vomited, then slept another hour. Upon waking she felt better and ate dinner. The difference between this migraine episode and last time is that although her headache is mostly gone, if she clears her throat or coughs or laughs, it really hurts her head over one of her eyes (forehead). This has gone on for a couple of hours and I don t know if I should be concerned. Could it be an aneurysm? Or is the fact that the intense headache went away after she took meds and slept a sign it was just a migraine? If it was an aneurysm, the throbbing headache wouldn t have subsided, it would be the same or would ve gotten worse, correct? Thank you.
