I would suggest that you maybe get to a Headache Specialist for proper diagnosis. And ask your neurologist for the actual name, because 'Migraine on Steroids' doesn't tell you what it is.
You need a full neurological work up, MRI, CT scan, all of that, because what you have may be entirely curable or, it could be something that needs immediate treatment. Please take care of yourself.
Do the triptans help the headache at all?
Is it only 1 headache that lasts for 3 days every 45 days?
