Aww Barb sorry to hear there getting worse. I used to get migrains when I was younger not to the same severity but still felt lowsey. My parents took me to a specialist who suggested keeping a diary of food intakes and activities. This lead to finding out that Milk seemed to be a trigger so I stopped all dairy in my diet and they stopped. A few migrain free years later I started dairy again and luckily I have not had any with it since. I know you have tried diaries and such in the past but just to let you know they can go as soon as they started. I think I was just lucky and grew out of them as they say some people do. Hope you get in to see the specialist and maybe have a few more ideas.
Now silly season has finished and everythings back to normal hope to see everyone around the boards again
