Hello,
Welcome to HCM and thanks for asking your question.
As you are confirmed case of
migraine and you had done all the tests, which are normal, so you only require preventive treatment and active treatment during acute attack of migraine.
Prophylactic treatment is required if migraine attacks are more than 2 per month. If i were your treating doctor, i would have advised you to start betablocker (mainly
propranolol) and
tricyclic antidepressant (mainly amitryptaline, if migraine is severe) for 2 months and then review the condition.
During acute attacks, you can take NSAIDS,
Sumatriptan and if its resistant to these than you can take risatriptan, which is newer and very effective drug to control the acute attack of migraine.
As all these are prescription drugs, you need to consult a neurophysician and discuss the treatment guidelines.
Hope this helps and let me know if you have any further relevant questions, i will be happy to answer.
