Welcome to the Migraine Board. You can find a wealth of information and support here. There not much we haven't heard or seen on this board.
As for your question about Migranal. After 30+ years of migraines, I finally found Migranal nasal spray. It is my saving grace. It is my MIRACLE!!! I literally have tried and failed to sucessfully manage my migraines using practically every medication every used for the treatment of migraines. You name a medication, I've tried it or taken it for a while unsuccessfully. Just by accident, I tripped across Migranal during a trip to the ER for a severe migraine. The doctor gave me a cocktail of benedryl, compazine, dilaudid, and DHE(Migranal). It worked so well, I just couldn't believe it. I got my PCP to prescribe the Migranal Nasal Spray as an abortive, and it is just perfect for me. It's been a long hard road, but this drug is my pot of gold at the end of the rainbow. I can't recommend it more highly.
I would try it for yourself by all means. No side effects, no rebound, no negative anything. I hope this works as well for you as it has for me.
Please keep us updated on how you are doing.
