I have been in the ER quite a few times myself with my husband by my side - tell him not to give up there are so many new techniques and medicines and I was also getting headaches 3-5 times a week and they were just running into each other they even did a Cat scan on my brain to see if I had a tumor once the pain was so bad I was crawling on the ground and
I could not stand - my husband did know what to do.
There are a few elements that we can control
1) diet - pay attention to the foods that trigger a migraine - I cut out a lot from my diet
2) reduce the stress if possible
3) smoking is not good for migraines
4) Keep on your GP doctor to formulate a plan.
I wish him the best of luck :)
