My Neurologist once told me "migraines are like fingerprints. No two people suffer from them
exactly alike."
In otherwords, everyone suffers from them in different ways. Reason why it is hard to treat & difficult to find the right and/or correct combination of drugs to control the pain (there is no cure for migraines).
Took me 6 years to find the "right combination of drugs" through a Migraine Management Programe to control my migraines to a comfortable level.
I had to be "weaned" off of Excedrins *first* because they were the cause of "Rebound Headaches".
